Broken cPanel Installation

Hello,

First of all I wan to introduce myself. I am Ovidiu, I'm from Romania and I am the senior admin of a small hosting business.

First of all I want to apologize if this issue was discussed/explained somewhere else. I am new here.

Our web developer decided to leave us a few days ago without notice and left us with a broken WHM installation.

The issue is as follows: The day after he left 60% of our shared webhostings went down without any clue about why.

The error is the following:

Code:

This site can’t be reached
example.org refused to connect.

ERR_CONNECTION_REFUSED

The following day 100% of them went down.


What I am asking for ?


I never worked with WHM or cPanel in my life and seeing the admin page of WHM made me a bit dizzy. I need to find a way to troubleshoot this error.

What I tried so far:

Checking logs. (nothing related to the downtime there as far as I can tell)
Rebooting. (Hard, soft, forceful, graceful, you name it I've done it)
Upgrading to the latest version(why not ?)
FaQ(/scripts/upcp /scripts/fixndc)

Help me please. I am the noobest guy ever when it comes to WHM but I am stuck with clients begging us to fix the services. Everyone can learn WHM and cPanel but starting it like this is no easy task.

Thank you very much for your time!

Ovi

 

Dear Michael,

Thank you for replying.

It seems that csf is already installed and I tried flushing it without success. After I flushed it I tried disabling it alltogheter but with no results sadly...
