mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)
/home/andrew/public_html/includes/class_core.php on line 273

What is this error? And how can I fix this?

This error means either:

1. The info in your config.php file is wrong (in which case your forums wouldn't work at all), or

2. MySQL crashed, it's not running or it can't find the socket. You need to contact your host about this. Here is more info on this error:
