I have had several isp_config servers running fine without issue for several months. The perfect setup for FC4 and the installation guide worked first time every time. Great work.
One of my servers has just developed a problem with the admin login interface. I can no longer login.
I goto https://my.tld.com:81
and attempt to login.
Username admin - and I enter the wrong password on purpose - I get an err101
Username admin and the RIGHT password - I get redirected to a file that does not exist: /login/login_fehler.php
(I know that it is the right password as I reset it using mysql)
I do not have this file on my other ispconfig servers....
And AFAIK nothing has changed in my environment....
Nothing of interest in the logs, only the 404.....
