I'm trying to renew my rocket codes, they expired yesterday.

But i get a sql error every time. it lets me enter the codes i want to renew, and when i click submit it comes up with this:

Warning: mysql_connect(): Access denied for user 'payment_user'@'localhost' (using password: YES) in /home/papiao/public_html/renew/config.php on line 157
Access denied for user 'payment_user'@'localhost' (using password: YES)


What can i do?
