Cannot publish/create FAQ article – “Response is not a valid JSON response”

    Hi, I cannot publish/create new FAQ articles anymore (previously I was able to, around two months ago). I get the following error message shown in a red banner at the top of the editor:

    “Updating failed. The response is not a valid JSON response.”

    I am using the default block editor. My website is running WP 6.5.2, PHP 8.2. There are no related error messages that show up on my debug.log file. I have updated all my plugins. What could be causing this issue?

    Pulling my hair out right now. TIA!

    UPDATE: Found the solution! Apologies, it was not related to the plugin itself, but rather the configurations of my site.

    Hi @tanjasue,

    Please try to use Classic Editor plugin, and let us know if this resolves the problem for you.

    Thanks,

    Hi @tanjasue, sorry to hear that you’ve encountered the same issue!

    For me, the problem was due to a redirect rule that was set up on my WP host platform. The redirect was modifying the AJAX request URL when attempting to update/create an FAQ article, thus the block editor was throwing the “Not a valid JSON response” error.

    Might I suggest reviewing your site’s redirect rules, especially just in case any involve the URL substring ‘faq’?

    If that wasn’t the root of the issue, please try and see if any firewalls/security softwares installed that are blocking the AJAX request?
