Somehow the wpdiscuz-ajax.php file is blocked. Probably it's done by other plugins or by server-side.
Please 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.
@asti Hi! Thank you so much, it works now. May I ask any big difference if I enable the "Use WordPress native AJAX functions"? Will my site be slower or does anything change?
In any case, if you see some changes you can find the problem maker by disabling the plugins/theme one by one and checking after each deactivation. If none of the plugins/theme causes the issue contact the hosting support and ask them to check it.
