phpBB Authentication method not working
Hi all.
I'm new to TikiWiki and have been struggling to get the phpBB Authentication method to work.
What I've done:
I've set Login > Gen Prefs > Auth method to phpBB
unchecked/unticked > Users can register
Under the phpBB tab, I've checked/ticked:
Create user if not in Tiki  
Use Tiki authentication for Admin login
Disable Tiki users who don't have a phpBB login
And populated the database fields correctly, I assume. And I assume phpBB Database Hostname can be set to localhost since both db's are on the same server.
I've created a user in phpBB, logged into phpBB with user, then logged out. This was done since I didn't know at which point the user was created in Tiki.
Looking in Tiki, user was not created. Not sure if user is supposed to be created or not.
Logging into Tiki with created user gives me a white page with this error message: AuthPhpBB : Query failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1''
I'm using:
phpBB 3.1.5
Tiki 14.0
I've also tried with Tiki 12.4 with the same results.
If phpBB is to blame, what phpBB version is known to work with either Tiki 12.4 or 14.0?
At this point I'm not sure what to do next, or if I've set this up correctly. Any help would be appreciated.
Thanks.
