I am having the same issue. I have switched browsers and cleared cookies, but if I enter a bad password with the log me in automatically box checked I get the same error with the following URL:
https://ltac.org/mainpages/login.php?failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1&failedLogin=1
Is there a way to fix this, or should I just remove the log me in automatically option?
