We upload lots of images to WordPress daily as part of our content creation process. But sometimes, we come across errors like the HTTP image upload error.
We’re sure you may have too, and we know how frustrating it can be, especially when you’re in the middle of creating content. It can halt your workflow and leave you wondering what went wrong.
In this comprehensive guide, we’ll show you how to easily fix image upload issues in WordPress.
What Causes the HTTP Error During Media Upload in WordPress?
Many things could lead to an HTTP error when you are trying to upload images to your WordPress website using the WordPress media uploader.
Basically, WordPress is unable to figure out the cause, and that’s why it displays the generic ‘HTTP error’ message.
The frustrating thing about this WordPress upload HTTP error is that it doesn’t give you any clue about what may have caused it. This means that you will have to try different solutions to find the cause and fix the error.
That being said, let’s take a look at how to troubleshoot and fix the HTTP error during media upload in WordPress. Feel free to use the links below to skip to any of the methods to fix the error:

1. Try Uploading the Image Again
First, you should wait a few minutes and then try uploading your image file again to your WordPress website. This error is sometimes caused by unusual traffic and low server resources, which are automatically fixed on most WordPress hosting servers.
If that doesn’t work, then you may want to try one or more of the following:
- Refresh your browser or clear your browser cache.
- Resize and rename the WordPress image and upload it again to the media library. Check out our list of image optimization plugins to reduce your file size.
- Save the file in a different format. For example, you can change JPEG to PNG using image editing software. After that, retry uploading the file.
If following all these steps still results in the WordPress image upload error, then the issue is not caused by a temporary glitch and definitely needs your immediate attention.
2. Deactivate All Plugins and Your Current Theme
If you just installed a new WordPress plugin recently, it may be incompatible with your other plugins and disrupt the image upload process. To see if this is the case, you can deactivate all your WordPress plugins.
If the HTTP error disappears after deactivating a WordPress plugin, then that may be the culprit behind the HTTP upload image error. You can install an alternative plugin or contact the developer for support.
For more information, check out our guide on how to easily deactivate all WordPress plugins and how to deactivate plugins when the WordPress dashboard is inaccessible.
Similarly, sometimes theme conflicts can also disrupt the image upload process. Themes can include functionalities that might interfere with how WordPress handles media uploads.
Luckily, identifying a theme conflict is relatively straightforward. You can temporarily switch to a default WordPress theme. For more information, check out our guide on how to properly change WordPress themes.
Once the default theme is active, try uploading an image again. If the error disappears, then the issue likely lies with your current theme. In this case, you can check if a theme update is available. Often, updates fix compatibility issues and bugs.
Or, you can reach out to the theme developer for support. They might be able to provide a patch or offer guidance on resolving the conflict.
3. Increase PHP Memory Limit
WordPress is written in the PHP programming language. Additionally, the amount of memory allocated for different PHP processes is determined by your web hosting server.
If uploading images requires more PHP memory than is available, you may see the HTTP image upload error in WordPress.
To fix this, you need to increase the memory PHP can use on your server.
You will first need to access your site’s files using an FTP client or the File Manager app in your web hosting dashboard. Next, go to your root directory and find the wp-config.php file.
You will then need to edit the wp-config.php file using a text editor and add the following line of code to it:
define( 'WP_MEMORY_LIMIT', '256M' );
This code increases the WordPress memory limit to 256MB, which would be enough to fix any memory limit issues.
Finally, you must save and upload the file back to the server.
To learn more, please see our step-by-step guide on how to increase the PHP memory limit in WordPress.
4. Change the Image Editor Library From Imagick to GD Library
WordPress runs on PHP, which uses two modules to handle images. These modules are called GD Library and Imagick. WordPress may use either one of them, depending on which one is available.
However, Imagick often runs into memory issues, causing the HTTP error during image uploads. To fix this, you can make the GD Library your default image editor.
You can do this by simply adding this code to your WordPress theme’s functions.php file or using WPCode (recommended):
function 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' );
For more details, you can see our guide on how to add custom code in WordPress.
After adding this code, you can retry uploading files using the media uploader. If this doesn’t solve the issue, then you can remove this code and try other methods described in this article.
5. Limit Imagick by Editing .htaccess
This method allows you to control how Imagick uses server resources. Many shared hosting providers limit Imagick’s ability to use multiple threads for faster image processing. However, this will result in you seeing the HTTP error when uploading images.
An easy fix is to add the following code in your .htaccess file:
SetEnv MAGICK_THREAD_LIMIT 1
This code simply limits Imagick to use a single thread to process images.
6. Update Your PHP Version
If your WordPress site is using an outdated version of PHP, then it could trigger the HTTP image upload error. This is because newer PHP versions have performance improvements and generally use less memory.
Luckily, it’s easy to check your PHP version and update it. For more details, please see our beginner’s guide on how to update your PHP version in WordPress.
7. Check File and Folder Permissions
WordPress relies on specific file and folder permissions to function properly. Incorrect permissions can prevent WordPress from accessing or modifying files, leading to upload errors.
For instance, if the upload directory lacks proper write permissions, WordPress won’t be able to save uploaded images.
To ensure correct file permissions, check out our guide on how to fix the file and folder permissions error in WordPress.
8. Enable Debug Mode
Sometimes, underlying PHP errors can manifest as the HTTP image upload error, making troubleshooting difficult.
Enabling debug mode in your WordPress configuration will reveal any PHP errors in the debug log, providing valuable clues about the root cause of the upload issue.
For instructions on enabling WP_DEBUG mode, refer to our article on how to enable WordPress debug mode. This guide will provide step-by-step instructions on adding the necessary code to your wp-config.php file.
9. Check Your Hosting Resources
If your website reaches its storage quota or encounters limitations on server resources, you might experience upload errors. For instance, insufficient disk space can prevent WordPress from creating new files or folders needed for image uploads.
Most web hosting providers offer a control panel where you can view your website’s resource usage, including disk space. If you’re unable to see it, contact your hosting provider’s support team for assistance.
If you’re nearing your storage limit, consider optimizing your resources. For example, large image files can consume significant storage. You can optimize your images to reduce their file size before uploading.
If optimizing resources isn’t enough, consider upgrading to a hosting plan with more storage space. This will provide the additional capacity needed for your website’s files.
If you’re looking for a reliable WordPress hosting provider with generous storage space, Bluehost is a popular option. They offer various plans to suit different website needs.

This problem can be quite frustrating when a website owner can’t upload an image, and no one knows why at that moment. I’ve dealt with this issue about twice, and luckily, I was able to resolve it by adjusting permissions via FTP, which was the core of the problem. However, it’s good to know other methods and possible causes of the issue. I’ll definitely save this tutorial because I have a feeling it won’t be the last time I encounter this problem, and next time, it might not be folder permissions.

FANTASTIC!!! Every other search I did yielded nothing.
Godaddy hosting with wordpress installed. Killing imagick did the trick. My lightroom plugin is functioning like a trooper now.
Thank you so much, just had to share with you.

Hi,
I started having this HTTP uploading error for images that are larger than 600x900px . The size in KB doesn’t matter – 100KB or 300KB – they are uploading just fine if they are less then 600×900.
I have tried all the methods you described without success.
Do you think that changing the theme can help?
WPBeginner Support
You would first want to reach out to your hosting provider to ensure you are not running into a safety measure from their end that would cause the error.
Admin
George
Thanks!
I called them before posting my question – they told me to contact WP support. To me, it also looks like they installed something on their server but are not willing to admit it.
I’ll call again.

Tried all the above and no luck. My issue is only mp3 files, I get the http error. Contacted my hosting provider and they could find nothing wrong. Images upload fine. What am I missing?
WPBeginner Support
For MP3 files you may need to increase the memory limit to 512 in case it is due to how large the files are

SOLVED: my pdf files that would not upload into the Word Press media library with HTTP Error had file names with a semi-colon in them. I deleted the semi-colon and it uploaded just fine. Semi-colons are legal characters in Word docs and pdf files, but apparently won’t upload to Word Press for reasons beyond my knowledge. ; ; ; ;

You may want to ensure you didn’t change your homepage settings while troubleshooting and have you removed the code to see if that solved the missing content?
