Im talking about the issue where once someone is logged in, they close browser and comeback, and try to login again it tells them the are already logged in and to refresh the page, when they refresh they stay on the same page, thus they dont know what to do. Once someone is logged in, they should not be shown the login screen again, or when they refresh they should go to (username) page.
I am pretty sure there is a solution for it now, but how do I do it, some kind of guidance please.
