Support » Fixing WordPress » General 400 Ajax Error when Publishing or Updating Pages

  • I recently updated a handful of plugins and themes, and now I’m seeing this error whenever I update or publish a page:


    I’ve searched on the forum for this error for some insight, but I’ve seen variations of what number is listed after “GENERAL” (which apparently means it’s a different error, even if it still has to do with an AJAX call not working), and suggestions that involve waiting for updates. I’d like to know WHERE this is coming from so I know what possible plugins to disable (though I’m assuming it’s one of the ones I updated recently).

    I am able to publish/update posts if I click “Ok” on this error and press the Publish/Update button a second time (the error does not come up a second time).

    Does anyone have any suggestions?
