My list of banned IP's have stopped working since I upgraded to 7.3

I use wildcards extensively - eg. 122.164.% and that now fails to block new signups from those locations.

Is this a bug or was there a change in 7.3 that I missed?

Hmm, it seems somewhere along the devel cycle, the ban check was removed from the main ubbthreads.php script that checks for bans when a user isn't logged in.

Line 184 of ubbthreads.php you'll see this:

$user = $userob->authenticate($fields);

Right after that, add this:

$userob->check_ban();

Thanks Rick.
