A few days ago I started to receive a 403 error in WpDiscuz related to ajax, which does not allow to display the replies to the comments.

This error seems to be related to the communication between WpDiscuz and Cloudflare, although I personally have not made any changes to either of them. At least not consciously.

You can find the comments in any post of the website. The error happens in all of them. Example in this post: Cuadernos de estimulación cognitiva

I've revised Cloudflare firewall rules but I haven't seen anything wrong or updated recently.

Thank you in advance.

Somehow the wpdiscuz-ajax.php file is blocked on your website. It may be done by other plugins or from the server side.

Deactivate the plugins/theme one by one and check after each deactivation. If none of the plugins/theme causes the issue contact the hosting support and ask them to check it.

Alternative solution: navigate to Dashboard > wpDiscuz > Settings > General Settings admin page, enable the "Use WordPress native AJAX functions" option, delete all kinds of caches (CDN, website, wpDiscuz, browser) and check again.

In case you want to say thank you! 🙂
We'd really appreciate if you leave a good review on the plugin page.
This is the best way to say thank you to this project and the support team.
