Just upgraded yesterday, had to log back in then, and it was fine. This morning though, I can't log in. I've tried admin and another user. I don't get an "incorrect password" message, just a new blank login page.
I've tried resetting the password through the link on the login page, and I get my link and my new password, but they don't let me in either, just the blank login screen again.
I've also tried emergency.php which has worked for me in the past.
The only thing I haven't tried is changing the password in phpMyAdmin, but I don't think resetting the password is the issue. Can anybody suggest another option?
Thanks
