Script does not start to install

Hello, I don't know if it is the right topic for the problem I have, but please if anyone knows who can help me... I have a dedicated server, on which I installed centos 7.9 and Cpanel & WHM, I configured the packages, I added a domain, etc .. the problem is that on my domain I have a script that needs to be installed, the problem is that I can't install after I unzip it the script, I only see the "Index Of" window, but on localhost on my PC, with Xampp, everything works normally, it installs without any problem... since it can be the problem from WHM, I didn't configure everything must or what can be?
