The “HTTP Error When Uploading Media” is a common problem that users often face when trying to upload images or other media files to their WordPress websites. This error message can occur for a variety of reasons and can be frustrating for users who want to add visual content to their site.

Possible causes for this error include incorrect server settings, large file sizes, or conflicts with certain plugins. When you encounter this error, here are some steps you can take to resolve it:


  1. Verify the image file format (JPEG, PNG, GIF).
  2. Make sure that the image file you’re trying to upload is in a supported format, such as JPEG, PNG, or GIF. If the file is in a different format, consider converting it to a compatible one before uploading.

  3. Resize the image if it’s too large.
  4. Large image files can sometimes trigger the HTTP error. If your image has a high resolution or large dimensions, consider resizing it to a more reasonable size before uploading. There are various image editing tools available that can help you do this.

  5. Deactivate plugins temporarily to check for conflicts.
  6. Some plugins might interfere with the uploading process and trigger the HTTP error. To check if a plugin is causing the issue, deactivate all plugins temporarily and try uploading the media file again. If the upload is successful, reactivate the plugins one by one to identify the problematic one.

  7. Modify server settings or reach out to your hosting provider.
  8. Incorrect server settings or limitations on your hosting server can also lead to this error. If the issue persists, you might need to modify certain server settings or contact your hosting provider for assistance. They can help you adjust server configurations to accommodate media uploads.
