"Warning: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /home/domains/rs-i.net/user/htdocs/ubbthreads/mysql.inc.php on line 35 "
MySQL is not running, or in rare instances, the MySQL server is running but the socket has gone away. Both are fixed by just restarting MySQL. Your ubbthreads sql logs will not show you what's up. In this case you need the server's MySQL .err log.
