Hello dears, Please I need your support I have installed ispconfig but when trying to open it i get apache page OS:- Centos 6.9
Check with the perfect server guide you have installed everything and set up correctly. Check you set up the hostname as instructed.
Type hostname and hostname -f on your terminal and see what is the result, as from your post, they are not properly set, so ISPConfig installation did not finished correctly. You will also need to fix your default timezone settings in php.ini because it seems wrong too.
And this is a fresh installation? CentOS 6 is really really outdated, I won't use it for a new installation.
