Hello,
I have opened a support here regarding issue of wpdiscuz with commenting ( https://wpdiscuz.com/community/troubleshooting/no-comment-text-field-and-no-twitter-button-effect/#post-11270) . Turns out wpdiscuz is incompatible with WP Rocket which is more important for me.
I thus decided to remove wpdiscuz, but I now end up with a the "wp-comments-post can't be found" whenever I try to comment with the usual and old wordpress comment function way.
I have purged my cache, wp-comments-post still exist on my server, still with 644 permissions.
Does anyone have any idea ?
Thank you!
Please note wpDiscuz is a native comment system. It doesn't change anything in the Database and on the server-side as well.
Probably the issue was before installing the wpDiscuz plugin, thus the wpDiscuz hasn't worked you your website.
