Hello I am new to the Forums here.

I registered for a forum and it has been going pretty well actually, but there are times when the site goes down. I dont know what the reason is for it going down but it does. When It goes down I get this message. I have no idea what it means

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (11) in /home/freebb/config/multiforums.config.inc.php on line 10
Unable to connect to database on 'localhost' with user 'root'
Please check your settings in multiforums.config.inc.php!
Is this usuall, if not, is there anyway to fix this so I can stop having the downtime with my site.

Thanks Wnghs2007 (KC)
