Greetings,
Today there was a update on my computer for Windows I believe, and after installing it, I can no longer stay signed into the Pantheon forums. I use to be able to click on mutiple threads in new tabs but now if I am lucky I can get one tab to stay logged in and other tabs constantly tell me to re-log in. Even if I click the remember me box on log in it forgets me from page to page. Its now got past annoying because I prefer to open up mutiple tabs and read through them all then constantly re-logging in on evver tab I click. Took me 4 tries to even allow me to post this message because it would forget me by time I would get back to website support.
Please submit a support ticket my friend, the team will be able o have a look and help you out further - https://www.pantheonmmo.com/support/
