I have the following message returned when trying to access my subdomain I already changed the max_execution_time in PHP.ini from 30 to 90 according to some tips found. However, to no avail. I also tried to modify Max Requests and Max Children in Software-> MultiPHP Manager-> System PHP-FPM Configuration according to other tips found. However, without success too. Is there any other reason for this to happen? What can I do to resolve this? Thank you.

  I decided to do the following steps: I went to WHM-> Software-> MultiPHP Manager-> System PHP-FPM, clicked Turn Off, then On and clicked Convert All Accounts to PHP-FPM. It worked, solved my problem. But I still don't understand the purpose of this option and why it wasn't working. Can someone explain to me?

  Have you tried to look into the logs? /usr/local/cpanel/logs/error_log for example to see what wass causing the issue.

  You need to look at the logs to identify what is causing the error. Just changing things without actually knowing what is going wrong is not going to be a solution. I would start with the apache error logs at /etc/apache2/logs/error_log
  then check the php-fpm PHP logs at /home/$user/logs/
  and the actual PHP-FPM Logs depending on the PHP they are at: /opt/cpanel/ea-phpXX/root/var/log/php-fpm/error.log
