I just tried to change what you suggested, but I just managed to log myself out... tried changing the password while my internet connection dropped, maybe I mistyped the password, how do I reset the admin password for ispconfig ?

well after the hanges you proposed her is the result: I type in admin and my passwd:

Warning: include_once(/lib/classes/ispconfig_db_mysql.lib.php) [function.include-once]: failed to open stream: No such file or directory in /home/admispconfig/ispconfig/web/login/login.php on line 32

Warning: include_once() [function.include]: Failed opening '/lib/classes/ispconfig_db_mysql.lib.php' for inclusion (include_path='.:') in /home/admispconfig/ispconfig/web/login/login.php on line 32

Fatal error: Class 'db_mysql' not found in /home/admispconfig/ispconfig/web/login/login.php on line 34

BTW, why does it say h5810.serverkompetenz.net.h5810.serverkompetenz.ne t instead of h5810.serverkompetenz.net?

I just tried accessing my ispcfg without https only http and it is configured for https, the error looks like this:

Bad Request
Your browser sent a request that this server could not understand.

Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

Hint: https://h5810.serverkompetenz.net.h5...petenz.net:81/

well I do not know, I guess it has something to do with the hostname settings?
