I got a
Debian 8.11 vServer with
With the server I received a gratis domain.
I bought an extra domain and set it's A records to the vServer IPv4 address.
For the extra domain I have a valid SSL certificate that I installed.
Accessing certain directories / files on my webserver from my browser show different results depending on the domain I'm using.
http://188.8.131.52/phpmyadmin/ - Showing me the index page, too
Now other directories work on all 3 domains for some reason.
And the weirdest part is: Without having changed anything, a 500 error that occured at a certain path with a index.php using my new domain randomly disappeared after awhile.
Been trying to find the cause of this for a while now.
