[Forum] Changing Forum URL via mysql?

[boro_boy]

I have my live forum running at www.myfootballforum.com

But my friend has offered me his dedicated server to use, so i've made a clone of the database and filesystem and transfered it over to his server. The site preview on plesk is:

https://s15290587.onlinehome-server.info:8443/sitepreview/http/myfootballforum.com/index.php

But its directing right back to www.myfootballforum.com

What is causing this? How can I make it stay on https://s15290587.onlinehome-server.....com/index.php


Thanks in advance
