Edit - it's worse than I realised. My post appeared on page 91 - but when I posted it added page 92, which doesn't have any posts on it. When I deleted my post it went back to normal, but when I posted again it did the same. Page 92 for some reason exists but has no posts on it - which gives you the error when you try to view it.
Edit2 - posting another reply fixed it, because the reply of course went onto the blank page 92, making it viewable. This crazy board and its crazy problems
