New pages = 404 page not found

I’ve just moved to a new server. I have 12 sites, all using wordpress 1.5.x. The move was successful for all sites, except one that I’m having a problem with. I added a new page, but when I click on the page from the menu, I get a 404 error. I checked the database using phpmyadmin and the post is definitely there.

On this particular site, I’m not adding POSTS, but am using the PAGE feature. I tried adding a post to see if it worked and it DID work. So it’s just the PAGES that I’m having problems with. I’m hoping to make that clear, in case it helps find the problem 🙂

I made several test pages and have the same resulting error, but once again this is only with one of my wordpress sites, not the rest. On this site, all of the old pages still work from the menu. I only get the 404 error with new pages. Something went wrong somewhere and I don’t know where to begin. Can anyone suggest something?

thanks!
