For. years I have had our forum at aoai.org/forums set to manually approve all new forum users by me.  But now the new users are automatically being banned, which never happened before.  This seemed to have happened after I upgraded to the current forum software.  I don't see where I can change this, and is very frustrating.

Look at your Spam Prevention settings.  If one of the settings is set to register but ban, this behavior would occur.  

 

Thank you!!  It took me a bit of searching to find the spam defense settings, but I saw what was causing new registrations to be immediately banned.   This is now changed and hopefully will be good now.

This apparently must have been reset when I updated the server software.
