I actually think this only happens when the dev refreshes something on the site. He's been working like mad to fix all kinds of bugs and every time he uploads new code, I think we all get kicked. I think.
Let's give it a few days. If you're still having the issue a week from now, let me know. Also, what someone else said about saving the password is correct. Others aren't affected by it because their browser signs them in right away, even if they do get kicked. If you're on a private device and can save the login info, it'll put an end to it.
Haha. That happened a long time ago. Had it not been so, and my mind was intact when I started this project, I never would have started. *wild laughter*
It has still happened to me, even when I haven't closed the window OR turned off the computer. That just happened today, and I do click the "remember me" box when I sign in again.
