Troubleshooting WordPress Media Upload HTTP Errors

Generic errors can be frustrating. This is especially true when you’re trying to do something as simple as upload an image to your WordPress site.

To get you back up and running as quickly as possible, here’s how you can get those media upload troubles solved.

Try Another Browser Window

This one sounds silly, but it’s the easiest one to check for. For security, WordPress uses nonces when anything is uploaded. If there’s an issue with the nonce, it’ll fail.

By loading the page in a new browser window, you can do a quick check to rule out any nonce issues.

Try a Smaller File

Here at Pagely, your default file upload size limit is far higher than your image would be, but there’s always a possibility that the issue is caused by the file size. Before doing any deeper troubleshooting, try uploading a smaller file.

The smaller the image file, the more accurately you can determine if file size limits are the culprit.

Check the File Type

Are you sure you’re uploading an allowed file type? Double-check the file’s extension to make sure.

If you want to be extra thorough, grab a random PNG or JPEG image from Google Images and try that. Just be sure it’s a small one or else you might run into file size issues.

Disable Plugins

You might have a plugin that’s interfering with your upload. Inside your staging environment, try disabling any plugins that might be getting in the way.

Once you’ve narrowed down the plugin that’s causing the issue, you can take further action to fix the problem.
