Your thread is not closed you keep losing it Installation Problems, having trouble
I dont know what more I can add here. I am logged in fine as in I go to your forum use the credentials you post and then go to your classifieds and I am logged in fine. You must go to admin of both programs and verify your cookie settings are as I noted in that thread and the login will definately be carried throughout and I already show that it is. Is your classifieds set to the same cookie settings your forum is set to?
