Failed to Upload Image Data to Cloud Server
As with any platform, there are always those annoying errors or problems you have to learn how to piece of work through. Trust us, we've pretty much seen them all! From the white screen of death to database connexion errors, WordPress definitely has its quirks. 😉 But we still dearest it! Today we're going to dive into 1 of the more mutual ones, theHTTP error. Users typically run across this when trying to upload images or videos to the WordPress media library.
While the HTTP error is unremarkably easy to gear up it tin be rather frustrating every bit it usually interrupts your workflow. Nothing is worse than spending xx minutes trying to notice that perfect image for your weblog post, you go to upload it, and bam, you're all of a sudden met with a very vague error.
Below we'll explore why this error happens and what you lot can do to quickly resolve it so you tin can get dorsum to uploading your media.
What is the WordPress HTTP Error?
The WordPress HTTP error occurs when something goes incorrect while attempting to upload images or videos using the built-in media library tool. Unfortunately, dissimilar browser errors where nosotros can usually reference an HTTP status code, WordPress errors are sometimes a little harder to troubleshoot (especially if you don't know how to enable WordPress debugging mode).
The very vague "HTTP error" definitely doesn't help yous determine what might exist incorrect or even where to start looking. But that is because at that place could be a few causes for the failure and WordPress merely doesn't know why, and so it spits out a generic error bulletin (as seen beneath).
How to Prepare the WordPress HTTP Error
From our feel, the WordPress HTTP error typically originates from two things: the first is aclient-side or user error (your login session, bad characters in the file name, etc.), and the second is aproblem or setting on your WordPress host(server issue, retentivity list, tertiary-party plugin, shared hosting throttling resources, etc.). Then nosotros'll dive into a little of both.
Here are some recommendations and things to cheque to fix the error (sorted in order past most common reasons we come across):
- Refresh the Folio
- Compress or Resize the File
- Rename the Image File
- Temporarily Deactivate Plugins and Theme
- Ask Your WordPress Host
- Increase PHP Memory Limit
- Cheque Uploads Folder Permissions
- Move to the Latest Version of PHP
- Fix Performance Bug with Imagick and Shared Hosts
- Remove Custom Media Library Path
- Disable mod_security
- Install the Add To Server Plugin
ane. Refresh the Folio
The very showtime matter y'all should practice when encountering the WordPress HTTP error is to simply refresh the folio in your browser. Sounds as well easy right? 😉 Well, actually this is the most common fix we've seen for information technology. Here's why:
Starting time, for whatever reason, your browser might have lost connexion temporarily with WordPress and the process simply failed to consummate. This could exist due to your Internet service provider, a temporary hiccup with your WordPress host, etc. If you refresh the page and effort uploading again it the mistake sometimes volition resolve itself.
Second, nosotros've besides seen that sometimes later refreshing the page, or coming back to the WordPress editor from another tab, that it suddenly kicks y'all out. This is about likely an indicator that your WordPress login session has expired. You lot should encounter the post-obit message:
Your session has expired. Please log in to continue where yous left off.
So naturally, y'all log dorsum in and try to upload your media again. However, the HTTP fault occurs. This is kind of a quirk with WordPress. Once you log back in, you lot demand to actually manually refresh the page you lot're on. Then uploading media will piece of work over again.
2. Shrink or Resize the File
You might need to edit your image file, which could entail reducing the file size (KB or MB) or decreasing the width/height (pixels). We recommend checking out our in-depth post on how to optimize images for the web. There are a lot of third-party epitome optimization plugins you can utilise to automatically do this for y'all (both reducing and resizing) when your image is uploaded to the media library.
We take used Imagify on our Kinsta site for years without a unmarried issue. But there are a lot of other great ones out in that location as well. Just make certain whichever plugin you lot use, that they are optimizing images on their ain servers, not locally. If yous're majority optimizing images locally this can drastically harm your site'due south functioning.
Information technology's OK to upload loftier-resolution images every bit WordPress supports responsive images out of the box. In fact, you will probably desire to then that the image looks well-baked on retina displays. Merely unless your a photographer or concern that needs high-resolution images a practiced rule of pollex though is to keep your terminal paradigm size under 100 KB and no more than than double the size of your website's content div width.
Likewise, you might have to play with the PNG and JPG file types. Sometimes ane can be much larger than the other depending on what type of image it is.
Depending on the configuration of your WordPress host, you might also want to look into increasing the WordPress maximum upload file size.
iii. Rename the Image File
It tin never hurt to attempt and rename the image file. WordPress should automatically append a number on the cease if you lot try to upload a duplicate file proper name, but in case that doesn't work, try renaming your file. Unfortunately, WordPress doesn't allow you rename the file of an already uploaded image file, and then you will need to rename it locally and re-upload it.
When we are uploading images that already exist we typically add a -i or -2 on the end (instance: image-file-ane.png, image-file-ii.png). Make sure to add the dash otherwise Google will read information technology as one give-and-take and it could hurt your SEO.
Also, to exist safe, stay clear of uploading an prototype with file names that contain special characters. This includes international language symbols and characters such as apostrophes. Dashes are OK. You can see in this example below on the Kinsta Japanese site, we are using English for the file names, non the special characters. While WordPress can technically support these, there are a lot of other bug that can pop up.
iv. Temporarily Deactivate Plugins and Themes
It'south always a good idea if you're having HTTP errors to endeavor deactivating your plugins and fifty-fifty switch your WordPress theme to the default to meet if this resolves the problem. A few plugins that are are typical culprits include image optimization plugins (they tie directly into the media library) and security plugins such equally WordFence (these plugins are sometimes also restrictive). Or y'all tin can simply delete your WordPress theme.
If you don't want to affect your live site, simply clone your live site to a staging environment. If the WordPress HTTP error is likewise happening on staging, then you can quickly deactivate all your plugins to commencement narrowing it down.
Remember, you lot won't lose whatever information if you simply conciliate a plugin. If you can still admission your admin, a quick mode to do this is to browse to "Plugins" and select "Deactivate" from the bulk deportment carte du jour. This will disable all of your plugins.
If this fixes the outcome you lot'll demand to detect the culprit. Kickoff activating them ane past one, and try uploading an image once more in the media library. When you see the HTTP error return, you've establish the misbehaving plugin. Yous can and then reach out to the plugin developer for help or post a back up ticket in the WordPress repository.
If you can't access WordPress admin yous can FTP into your server and rename your plugins folder to something similar plugins_old. So check your site once more. If it works, then you will need to test each plugin i by ane. Rename your plugin folder dorsum to plugins and then rename each plugin folder inside of if it, 1 by ane, until you discover it. Y'all could also attempt to replicate this on a staging site starting time.
The same goes for your WordPress theme. Typically themes don't necktie into the media library, simply we've seen some weird setups. Information technology never hurts to try switching your theme over to the default Twenty Seventeen theme to encounter if it fixes it. Just similar with plugins, you don't have to worry about losing your current theme settings. All of that is stored in the WordPress database.
5. Ask Your WordPress Host
If you've tried the steps above already and are still getting the WordPress HTTP error, we recommend reaching out to your WordPress host for assistance before proceeding. Many of the additional troubleshooting steps are a little more than avant-garde and a lot of times you lot can ask your host to exercise or bank check on this for you.
Kinsta's back up squad is available 24×vii from the bottom right-hand side of the MyKinsta dashboard.
six. Increase PHP Retentivity Limit
Another cause for the WordPress HTTP fault is that your server lacks the available retentiveness for the background upload process to consummate successfully. This is a very mutual problem with shared WordPress hosting. To fix information technology y'all need to increase the amount of retentiveness PHP can utilize.256 MB is recommended.
The default memory limit for Kinsta clients is already set up to 256 MB. If y'all host your WordPress site at Kinsta y'all shouldn't have any issues with a lack of memory. 👍
Increase PHP Retentivity Limit with wp-config.php
You can increment the PHP retentiveness limit by adding the following code to your wp-config.php file. Annotation: this may be overwritten by a server-level rule in identify by your WordPress host.
define( 'WP_MEMORY_LIMIT', '256M' ); Increment PHP Memory Limit in cPanel
If your host is using cPanel, y'all tin can increment the PHP retentivity limit in two different areas.
The first is under the software section. Click on "Select PHP Version." Click on "Switch to PHP Options." You tin can then click on "memory_limit" to change its value.
The second area is also under the software section. Click on the "MultiPHP INI Editor" tool. This allows you to modify the php.ini file. Just ringlet downwards to where it says "memory_limit" and input a higher value.
Increase PHP Retentiveness Limit with php.ini

If you aren't using cPanel, y'all can also edit the php.ini file straight if you have access. To do this, login to your site via FTP or SSH, go to your site's root directory and open or create a php.ini file.
Can't connect via SSH? Learn how to fix the SSH "Connection Refused" error.
If the file was already there, search for the "memory_limit" setting and modify it as necessary.
Some shared hosts might also require that yous add the suPHP directive in your .htaccess file for the in a higher place php.ini file settings to piece of work. To exercise this, edit your .htaccess file, also located at the root of your site, and add the following lawmaking towards the pinnacle of the file:
<IfModule mod_suphp.c> suPHP_ConfigPath /abode/yourusername/public_html </IfModule> Increase PHP Memory Limit with .htaccess
The .htaccess file is a special hidden file that contains various settings you lot can use to modify the server beliefs, right downwards to a directory specific level. If you lot don't have access to php.ini, we advise you try this adjacent. Commencement, login to your site via FTP or SSH, take a await at your root directory and come across if at that place is a .htaccess file there.
If there is you tin edit that file to and modify the "php_value memory_limit" value.
7. Check Uploads Folder Permissions
Typically when in that location is a binder permissions fault y'all should get a message in WordPress most information technology not being able to write to the directory. Notwithstanding, this might not ever be the case. If a WordPress site has been hacked or infected with malware, there could be a lot of issues going on with the permissions.
Tip: Kinsta offers free hack fixes for all clients. 😄
The principal folder yous're concerned with is your /wp-content/uploads folder, as this is where files are stored when uploaded via the media library.
Co-ordinate to the WordPress Codex, all directories should be 755 (drwxr-xr-x) or 750.
Y'all can easily see your folder permissions with an FTP client (equally seen below). You could likewise reach out to your WordPress host support team and inquire them to quickly GREP file permissions on your folders and files to ensure they're fix properly.
Make sure that if you lot manually update the permissions on this folder that you lot check both the "Recurse into subdirectories" option also as the "Apply to directories only."
viii. Motion to the Latest Version of PHP
WordPress officially recommends PHP vii.iii or higher. If y'all're non running on that, you lot're below the minimum requirements set by the developers of the CMS. 😮
We ever recommend running the latest and supported versions of PHP due to the fact information technology offers better security and performance, including bug fixes and functions that need to be deprecated.
Nosotros have seen older versions of PHP contribute to all sorts of errors, including the infamous WordPress HTTP error. At Kinsta you tin can hands change to PHP vii.4 with a single click in the MyKinsta dashboard.
If your host uses cPanel they might already have an option available to you lot to modify your version of PHP. Simply log in to cPanel and under the "Software" category click on "Select PHP Version."
Y'all tin can so select the PHP versions available to yous that your host supports.
ix. Prepare Operation Bug with Imagick and Shared Hosts
There are 2 different PHP modules WordPress uses for prototype processing: GD Library and Imagick (ImageMagick). Depending on what is installed on your server, WordPress may use either one.
The trouble is that shared WordPress hosts accept a lot of hidden resource throttling behind the scenes. That is the just manner they can cram so many users on the same motorcar. A common upshot people meet is that at that place are too few resources allocated to Imagick (ImageMagick). Hosts volition limit the ability to utilize multiple threads, hence resulting in the WordPress HTTP fault.
You can add the following code to the top of your .htaccess file, changing the thread limit value to something higher.
MAGICK_THREAD_LIMIT 1
Another choice y'all accept is to tell WordPress to use the GD library instead of Imagick. Yous can do this past simply adding the following code to your theme's functions.php file.
role wpb_image_editor_default_to_gd( $editors ) { $gd_editor = 'WP_Image_Editor_GD'; $editors = array_diff( $editors, array( $gd_editor ) ); array_unshift( $editors, $gd_editor ); return $editors; } add_filter( 'wp_image_editors', 'wpb_image_editor_default_to_gd' ); Nosotros'll be blunt. If you're having to tweak things like this it's fourth dimension to motion to a new WordPress host. Kinsta doesn't accept crazy limits like this in place and for the most role, you're only express by PHP workers. You shouldn't have to worry most these types of things as a website owner.
We utilize LXD managed hosts and orchestrated LXC software containers for each site. What this means is that every WordPress site is housed in its own isolated container, which has all of the software resources required to run information technology (Linux, Nginx, PHP, MySQL). The resources are 100% private and are non shared between anyone else or even your own sites.
Read more most how Kinsta is different than whatever other host you've tried.
ten. Remove Custom Media Library Path
It very well could be that your media library path isn't setup correctly. We typically see this when users migrate their local evolution site over to production. If you wait in "Media" nether "Settings" in your WordPress dashboard and see a file path value listed, go ahead and delete it and click "Salvage Changes." You desire your media to be stored in the default /wp-content/uploads folder.
Beneath is what it typically looks like. If you don't see a library path, then you're all good here.
eleven. Disable mod_security
Mod_security is an open source firewall that sometimes might cause the WordPress HTTP error to occur. You lot tin disable mod_security by calculation the post-obit code to the summit of your .htaccess file.
<IfModule mod_security.c> SecFilterEngine Off SecFilterScanPOST Off </IfModule>
If you're using cPanel, y'all tin as well disable it by clicking into "ModSecurity" in the "Security" section.
And then toggle the status from "On" to "Off" next to the domain you lot want to disable information technology on.
We e'er recommend using an enterprise-class and even so affordable WAF similar Sucuri or Cloudflare instead. You can read our recommendation for the all-time WAF settings here.
12. Install the Add together From Server Plugin
Last simply not least, if y'all're really in a bind and cipher else seems to be working, you lot tin can install the free Add From Server plugin. Perhaps you're waiting for a response from your WordPress host or a programmer on how to go the WordPress HTTP error resolved.
The Add to Server plugin will ordinarily go you around the mistake and could exist a practiced temporarily gear up, especially if yous're right in the middle of something important. Information technology was originally developed to allow y'all to add very big files via SFTP.Important: this plugin is no longer maintained or supported. Utilize at your own risk.
Summary
As you can see in that location are quite a few dissimilar means to gear up the WordPress HTTP error. Hopefully i of the solutions in a higher place worked for you lot and you're already back on track and uploading your media. If you continue to receive this error fourth dimension and time again, information technology might be time to consider upgrading to a amend WordPress host.
