Hi, I'm completely new here (and probably in a very wrong part of the board), but I was trying to open a website (rowing.ucam.org) which is a message board, but I get the following error:
SQL ERROR [ mysql4 ]
mysql_connect function does not exist, is mysql extension installed? 
An sql error occurred while fetching this page. Please contact an administrator if this problem persists.
The website is run by phpBB. I suppose it's very easy to solve, but even being quite into programming I have no idea how to fix it and would be very happy if anyone could help.
