The "HTTP error" when uploading images in WordPress is a common issue and can be caused by a variety of factors. Here are steps you can take to troubleshoot and fix the problem:
-
Reduce Image Size:
- Large images can sometimes trigger HTTP errors during upload. Try reducing the size of the image before uploading.
-
Check File Format:
- Ensure that you're uploading images in a supported format (like JPEG, PNG, or GIF). Other formats might not be accepted.
-
Check File Name:
- Avoid using special characters or spaces in the file name. Stick to letters, numbers, and hyphens or underscores.
-
Check Upload Directory Permissions:
- Verify that the
wp-content/uploads
directory and its subdirectories have the correct permissions (typically 755 or 775 for directories, and 644 or 664 for files).

Disable Plugins:
- Temporarily deactivate all plugins and try uploading an image. If it works, reactivate each plugin one by one to identify the one causing the conflict.

Check Theme Conflicts:
- Temporarily switch to a default WordPress theme (like Twenty Twenty-One) and try uploading an image. This will help determine if the problem is related to your current theme.
-
Check PHP Version:
- Ensure that you're using a supported version of PHP. Older versions may have compatibility issues with newer WordPress versions.
-
Check for Server Restrictions:
- Some hosting providers have restrictions on file uploads. Contact your hosting provider to inquire about any limitations.
-
Optimize Images:
- Before uploading, consider optimizing your images using tools like Adobe Photoshop, TinyPNG, or other image compression plugins.

Check for Server Configuration Issues:
- It's possible that there are server-level configurations or security settings that are causing this issue. Contact your hosting provider for further assistance.
-
Reinstall WordPress Core:
- If none of the above steps work, consider reinstalling the WordPress core files. Make sure to backup your database and files before doing so.
- Remember to always back up your website files and database before making any significant changes. This way, you can easily restore your site if something goes wrong during troubleshooting.
