Error and got 307 emails because of it
 

Can someone help me out here and tell me what on earth this is......

Database error in vBulletin :

mysql_connect() [function.mysql-connect]: Access denied for user 'matt_forumus'@'localhost' (using password: YES)
/home/matt/public_html/forum/includes/class_core.php on line 311

I have 307 emails because of it and its been happening for the past hour

I havent had a working forum at that address in a long time* could it be because i just deleted a database and user* because i had forgotten what it was for ?
