New domain with a backup of another database.

[Fready]

What i did today was.
Copied all my vb files from my cpanel for an existing forum.
Exported all the files from the data base.

Re uploaded all the new files and data base to a new data base and folder for a new domain.
Edited the config.php to the new data base.

But when I tried to log into the new Forum with the new URL it just redirected me to the old working Forum.

So how can I get this to work?
