Passster – Password Protect Pages and Content


I'm not sure that updating the plugin is the only cause, but it is a cause of this problem: the correct password ceases to unlock the content after an update and says "security check failed" or something when attempting to authenticate.  This causes a periodic freak-out of my customer.  To fix it I have to add and take away the whole-page lock...I think...  It's hard to pinpoint what I actually do that makes it start working again.


Periodically doesn't unlock. Buggy
