I have checked the actual database, and checked the config file...it says
$table_prefix = 'phpbb_';
I know...it would seem it is wrong, since thats exactly what the error says...but since I upgraded from phpbb2 to bb3, and used the same databse, I dont think my prefix is phpbb3_ ...
Could I have done something wrong in a previous step?
You dont think its because I deleted the entries in the pp usergroups table? If it was, I am not sure how to get it back...unless I go back to the original db backup I made before the upgrade...and start over..which I would love to avoid!
