Moving hosts

[Mellymonster]

Hey guys,

My forum is moving to a new host, or well trying too, and we are encountering DB errors... We have backed up the DB closed the forum down, and put it into the new host, we then did the Config.php file, and changed the DNS, then comes the db errors, it takes about 15 minutes, and then db errors started coming.

The errors are like this

Database error in vBulletin :

Cannot use database newsite_christgarden

MySQL Error : Access denied for user 'newsite_christ'@'localhost' to database 'newsite_christgarden'
Error Number : 1044

Referrer :

Does this mean that the $config['MasterServer']['servername'] = is wrong?

We had it with another servername, and I was getting this error

Database error in vBulletin :
