Basically, on the 4.2.4 version I can't login, the page just refreshes without any error and the token changes. No errors in logs.
Every previous versions work.
This is Michal's patch:
https://github.com/phpmyadmin/phpmyadmin/commit/e6f6dab3b096e78d8118b29495085753a9095d2d.patch
It runs fine on my server with the mcrypt extension deactivated, but we would appreciate a confirmation from one of the reporters in this ticket, because we plan to release 4.2.5 quickly.
I tested the patch to libraries/plugins/auth/AuthenticationCookie.class.php on my 4.2.4 version of that file and it appears to work.
