ISPManager - display_error option and server shutdown?

Question

Apache HTTP Server

Hello!
Relatively recently, I rented a dedicated server on the FirstVDS.ru service, everything was very convenient, easy and simple. I paid already for the second month and decided to enable the option to show php errors in the server settings. As a result, the server crashed, the site was unavailable. I reloaded it. It didn't help, but I think I'll wait. I waited a few days and nothing changed. Then I decided to write to support, where they answered me like this:

Hello,
I see that the panel is working for you, and the server is pinging and available via ssh:
[email protected]:~$ ping 82.146.63.137

This answer freaked me out a little. I decided to fix it myself (I have no special experience in this).
Accidentally I went to the Tools > Services tab. And I saw where the process name apache2 number is 0. Why? Should it be?
Actually the question is how to restore the work of my site?
Thank you very much in advance!

There is a function that converts JSON into an array. And then $arr[ 'userId' ]
