Okay, so you got the annoying “response is not a valid JSON response” error message and are unable to upload pictures or images in your WordPress blog or website? Here are the possible solutions to solve the problem:
- Check for Conflicting plugins. You can do this by troubleshooting, deactivating, and then reactivating all plugins one at a time to determine if a conflicting plugin is the culprit.
- If you are using Google Accelerated Pages, then you should check your AMP settings: You might have just deactivated your Google AMP plugin. If that is the case, ensure that the AMP settings in your theme settings to redirect mobile users to AMP are still turned on. The reason for this is so as not to mess up existing links, which is also a culprit.
- Last but not least, check your permalink settings. Ensure it wasn’t changed from where it previously was. For best practice, the permalink structure should be set to Month and Name, that is, year/month/post-name.
Hope the solutions above were able to solve the problem of “response is not a valid JSON response” and you are now able to upload your images, pictures, and media, and also use your WordPress blog or website normally.
