Apache is not running on CentOS 7 Server

I'm running a Bitrix server over a CentOS Linux 7.4.1708 machine and I can't manage to get Apache work properly. I've tried restarting the Apache service but it didn't work.

I've checked the system logs via Webadmin and it shows the following:

I don't have any clue on what the problem might be. Apache used to work fine until we installed a Bitrix update on the server.

Any sort of help or comment about this would be much appreciated.
