I had a site which was almost finished, then added the blog.

When I try to access any page on the site (including the blog) I get redirected to the 'no pages found' error page. I have content there, and I can preview it through the editor just fine.

I've since uninstalled the blog, but the problem still persists.

Please could anyone point me in the right direction on where to look to try and resolve this? The site was almost ready for launch and I am dreading having to re-create it at short notice.

Thank you for any help!
