Persistent error: This comment is not acceptable

Hi,

Please look into an issue where wpDiscuz 7.6.67—with Akismet 5.7.2 activated—triggers the error This comment is not acceptable for any comment from any guest, regardless of the IP address. The comment does not appear on the frontend; instead, it goes straight to Comments --> Spam.

The same thing happens with the latest wpDiscuz 7.6.68, which displays the error message defined in the Message if comment was marked as spam field.

This is clearly a conflict with Akismet: everything works perfectly when Akismet is deactivated.

This didn’t happen before!

P.S. There have already been a couple of threads discussing this (see here and here), but unfortunately, you persistently attribute this bug to user settings or other site configuration specifics.
