I installed 2.2, upgrading from 2.1 and am getting this error when I enable debug mode. Not sure what to do or what this means:

Fatal Error in Gdn_Database.Connection();

An error occurred while attempting to connect to the database
could not find driver
The error occurred on or near: /home2/pbisworl/public_html/PBISWorld-forum/library/database/class.database.php

Welcome to the community.

Could you say what version of PHP you are running?

peregrine

Apparently it can't find the driver

make sure you have this module installed

pdo_mysql

in your php.ini or one of conf files you may need to point where your extensions are.

perhaps you upgraded php but didn't set drivers.

list your steps of what you did to install and if things worked correctly prior to updating vanilla.

run phpinfo() and it should provide necessary info.

list your Operating System
what version of mysql
as as whu606 says your version of php

Thanks for everyone's help and suggestions. I am on hostmonster and was running php 5.6 according to my php config. I looked into my php.ini file which indicated php 5.4, so I regenerated my php.ini file and that seems to have cleared everything up. Thanks for pointing in in the right direction and helping me to get my forum back up and running: http://www.pbisworld.com/forum/!
