I had already tried it like that but what happens is this:
If I try and login into myIP:81/phpmyadmin it succeeds but I only see a blank screen with this url: https://h5810.serverkompetenz.net.h5...81/phpmyadmin/
when I log into ispconfig go to MANAGEMENT and hold the cursor over BACKUP DATA, CHECK DATABASE, etc. the cursor changes to a hand to indicate a link, but if I hover over ANYTHING below SYSTEM CONFIG the cursor does not change and I cannot click that link - somehow all those links are lost - ???
