If you see an error similar to:

phpBB : Critical Error

Error creating new session

DEBUG MODE

SQL Error : 1054 Unknown column 'session_admin' in 'field list'

when accessing your forum you will need to upgrade your version of phpBB When a phpBB install has been upgraded from phpBB 2.0.11 to phpBB 2.0.16 a special install procedure must be done on the VPS. I have performed the following series of steps on your VPS for the domain mustardseedacademy.com:

1) Log into a shell prompt for your VPS.
2) Type the following command in the shell prompt:

cp -R /usr/share/doc/phpBB-2.0.16/install /var/www/html/phpBB2/

3) Go to the following URL in a web browser:

http://yourdomain.com/phpBB2/install/update_to_latest.php

4) Repeat step 3 for any other domains you wish to use phpBB.

5) Type the following command in the shell prompt:

rm -rf /var/www/html/phpBB2/install

At this point you should be able to access your forum at:

http://yourdomain.com/phpBB2/

Substitute your actual domain name for "yourdomain.com" in the above instructions.
