I just upgraded to Movable Type 3.1, but despite that fact that I have the “Enable Unregistered Comment Moderation” field unchecked in the configurations, it’s still insisting that I approve all incoming comments. Has anyone else had this problem, and did you find a solution? If so, drop me a line … or tempt fate by — ha! — letting me know in the comments.
Update: Fixed! Thanks to everyone who tipped me off to the MT 3.x / mt-blacklist 2.x incompatibility — that was, indeed, the problem.
