I am running a test upgrade of 3.4.9 to 4.1.19. This test install is in a sub directory of the forums I'm testing this upgrade on. I just got everything installed and it ran all the background processes. I click on the forums and then tried to sign in and it said it couldn't find that page. Anyone know what I need to check? I turned off FURL and mod rewrite on my 3.4.9 forums and still the same. Nevermind, fixed my own problem by turning off FURL on the new installation.
