Receiving emails about Database error

[Farman]

Hi

Recently I transfer my vbulletin site from one dedicated server to another but now I'm receiving emails regarding database every minute. And the forum is running ok.

Database error in vBulletin :

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Access denied for user 'stuffloa_forum7'@'localhost' (using password: YES)
/home/stuffloa/public_html/includes/class_core.php on line 311

MySQL Error :
Error Number :

Are you sure your user stuffloa_forum7 has all the proper rights for that particular database?

Yes it has all the privileges , It was working fine on my older dedicated server, working fine on the new also but theres some thing wrong that's why I'm receiving the emails.

I tried to make a new user for database "stuffloa_forum" and change the detail in config.php file, But I'm still receiving the emails of user "stuffloa_forum7" access denied.

The MySQL server is rejecting your authentication details. Double check that the database name, database username, and database password are all correct.
