Moved wordpress 2.7 from localhost to server, problems!

Ok, I had wordpress installed at https://localhost/wordpress/ and everything worked fine using it as a CMS for a company website.

I exported WordPress in Tools > Export, created a fresh install at https://dev.rawfusionltd.com and imported posts, pages, etc.

Heres my problem. The front page shows fine, and is showing the 3 most recent posts on the homepage, and the footer sitemap is drawing in all the pages. However, if I click on any link I get a 404 error page (likewise if I manually type in the post or page id, so I’m assuming it isn’t a permalink problem). The posts and pages all show up in the admin so I know they’re there, but if I try to preview either posts or pages I end up with the 404 again.

I’ve checked all my settings and they seem to be identical to the settings used on the local install which is perfect (obviously with the links changed). Only thing I can think of is that on the local install it’s in a sub directory and the live install is in a sub domain, but will this make a difference?

Any ideas would be great, I’m pulling my hair out here.

Thanks
Lee
