Hi @perfectfit , thank you for reaching out.
With Wordfence activated, could you please request one of the users to attempt commenting on a post, then head over to Wordfence > Tools> Live Traffic (Expand All Results), if Wordfence is blocking this, there should be an entry that explains more about the traffic and why Wordfence took the actions it did. Please share a screenshot of any blocked entries and share it with me.
There’s also a possibility that this could be a false positive. Sometimes, plugins or themes may exhibit behaviour that resembles known attack patterns, resulting in the Wordfence Firewall blocking something that is not malicious. I suggest we try switching the Firewall to Learning mode, as it might help Wordfence allow comments on the post.
From the Wordfence Dashboard, click on Manage WAF. Then, you will see Basic Firewall Options > Web Application Firewall Status. Change the option to Learning Mode. Now proceed to post a comment. This will help Wordfence learn that these actions are normal and will allow them in the future. After you have finished the user registration, switch the WAF from Learning Mode back to Enabled and Protecting, then test to see that users can still comment.
https://www.wordfence.com/help/firewall/learning-mode/ is an amazing resource for learning more about the WAF and learning mode.
Thanks,
Mark.
