I tried to install phpBB2 Board, but it said:

phpBB : Critical Error

Could not connect to the database

This is what I filled in:

Database Name: pcplay_tmn
Database Username: pcplay_tmn
Password: ******


What could have gone wrong?

IF tommy has set up a database for you.
the info you will need for phpBB2 is as follows:

DSN = localhost
DB Name = pcplay_tmn
Username = pcplay_tmn
Password = ********

if that does not work, then make sure that tommy has a database setup for you. it is possible that you did not request on at sign-up in which case you do not have one.

Already taken care of, thanks :)
