I just installed Mambo on Lunarpages through Fantastico. The install went fine. I have not switched the DNS for my current site to the site that will be hosted by Lunarpages - I was hoping to develop the site first using Mambo and then make the DNS switch once the site is finished.
When I try to log in to the Mambo Administrator '
http://oberon.lunarpages.com/~sitename/administrator' I get the error below. I assume this is happening because the URL for my site 'sitename.com' is not the same as
http://oberon.lunarpages.com/~sitename/Any suggestions?

Do I have to change a config file or something to get the mambo administrator to work before I switch the DNS?
Thanks...
