Problem with site urls – help!

I’m having a problem with my websites – a minor problem compared to what happened over the weekend, but a problem none the less.

When I visit my other blogs that are installed on the directories of Feverishthoughts the primary domain being used on my web hosting account also shows in the address if you click on the header on one of the blogs.

By this I mean you can get to WebStyle by typing in http://feverishthoughts.com/webdesign/ and the url looks normal, but if you click on the header or the home tab while on the site you’ll get an url that looks like this:

http://feverishthoughts.thewebfiles.com/webdesign/

Also, if you visit the first url without adding the / at the end of the url you’ll be taken to the second url that I listed with my primary domain included in the url.

This was happening when I was on my previous web host too. I’m not sure when it started happening but it’s been at least month. It could coincide with my upgrading my WordPress installations to the latest versions, or it could have something to do with lunarpages moving my sites to another server at the end of June. Perhaps when they transferred the site a little bit of coding got messed up and now that my complete site has been transferred to my new host – HostGator via a c-panel full account back up the problem persists.

The funny thing is that this doesn’t seem to be happening on my gardening blog or my husbands guitar related blog, but on all the other sub-directory blogs. Could it be something in the sites themes? WordPress or a hidden redirect?

The support team at Hostgator tried to take a look at this for me but they kept trying to change my htaccess codes and I’m certain it’s not something in my htaccess coding.

I’m pretty sure that I could add a redirect line to the htaccess for each of the troublesome blogs, but I think that there’s some underlying problem causing this too.

Help!
