WordPress install names muddled up

Hey there

I have muddled up the domain names with which I registered a WordPress installation and can’t figure out how to fix it. Can someone advise me, please?

I registered a site to the domain name samw.org.uk, but I didn’t point the name servers to the webhost straightaway. I parked a domain name on the site, petro-city.co.uk, and set up a WordPress installation and began creating the client’s website. Then some weeks later, I pointed the samw.org.uk nameservers to the webhost.

I have been using the parked domain name to access the site, and it has worked perfectly well. When I tried the samw.org.uk domain name this took me to the site, but showed the petro-city.co.uk domain name. I didn’t think to tackle this at the time.

Now, last night I attempted to remove the unparked domain name, petro-city.co.uk and use the original name, samw.org.uk. I got an error saying:

[QUOTE]There was a problem removing the parked domain Show Details
Error from park wrapper: Unable to find out which user owns the parked domain petro-city.co.uk. [/QUOTE]

The host has managed to remove the parked domain, petro-city.co.uk, but now the site doesn’t work at all.

The webhost and I think the problem must be in my WordPress installation, somehow, but where I’m not sure. Does anyone out there have any idea how to fix this?

Thanks you in advance

Sam
