Every time I close my browser I have to log back in. Cookies are still enabled. nothing Changed on my end... odd...
Same thing for me, no longer will automatically log in when I visit the site.
I just logged in manually, got a thank you for logging in then when I tried to respond to this thread got a message that I either needed to log in or didn't have permission to access the page. I logged in again manually and was able to respond to the thread.
