There was a minor major problem with Deny Posting Text and BBcode Until x Posts v1.0.1 which didn’t allow users to post anything as it kept giving them the BBcode not allowed until x posts message. So update to v1.0.2.
The problem was that instead of
[php]if ($post_message != $newmessage) {[/php]
it should of been
[php]if ($post_message != $bbencode_message) {[/php]
