    * JAuthentication::__construct: Could not load authentication libraries.
    * Username and password do not match

    Default A bad keystroke kills

    I could not login from either front end or back end with any level user name.

    In my case, under Global Configuration/System/System/Session Settings/Session Handler, I had inadvertently toggled over from "database" to "memcache" while making some other intended changes that I then saved. Upon saving, I was immediately tossed out from the backend and could not log back in.

    Solution was to use myPHPadmin to change configuration.php line item back to correct setting:

    $session_handler = 'database';
