I first attempted upgrading from vb4 to vb5 beta. All of the forums on the first page are present. After the first page, every link I clicked on was leading to a 404 - "The page cannot be found" error. I also noticed that the admincp had been moved to the core directory.
I then wiped these files and started again. Instead of connecting to the old existing database, I created a new one and tried to do a fresh install from scratch... Same problem... The first page loads fine. After the first page, I get nothing but 404 errors. Anything I click on including the login gets 404 - The page cannot be found errors.
I'm pretty lost. I've seen similar issues on this board, but I didn't want to hijack some one else's post with my own questions.
