My Wpdiscuz shows Nonce Invaild when logged in users leave comments, no prompts when visitors leave comments, but again, no comments. The default comment area of WP can be used normally after Wpdiscuz is uninstalled.
Hi,
Something blocks the native WordPress admin-ajax.php file.
Please check your security plugins' options and make sure they don't block the WordPress AJAX. This could be also blocked by the .htaccess file.
If none of the plugins caused the issue please contact server support and ask them to check the access of the admin-ajax.php file. This also can be done by the server side.
We have not received a reply from you for over a couple of weeks, therefore we will be closing this topic. Please create a new one if you require any additional help.
Thank You!
