I've got a brand new phpBB2 install with Categories Hierarchy, and a brand new, clean roster install with my guild uploaded and exactly one user's data (mine own).

When I turn phpbb_login authentication on, after installing it as per the install.txt doc, I get this when I try to hit the page not logged on as anyone:

Could not query PHPBB Config information
SQL:

File: addons/phpBB_login/inc/login.php

I have done the install three times to make sure I wasn't doing something stupid. My roster and phpBB are in the same database now.

Thoughts?

Thanks!

I'm not sure why are you are getting this error, other than maybe because it is a fresh install of phpBB.

Do you have direct access to your database? And if so, can you check to see if the table phpbb_config has any rows in it?

It is funny, because it didn't throw an error connecting to the database which is where I would expect it to bug out if it was going to have a communication issue.

Let's try to modify the error return to further debug this.
Line 127 should be
die_quietly("Could not query PHPBB Config information", 'Roster Auth', __FILE__,__LINE__,$sql);
Change it to
die_quietly("Could not query PHPBB Config information (". $this->database->sql_error->message .")", 'Roster Auth', __FILE__,__LINE__,$sql);

Perhaps that will give us some further insight into the error.
