I just installed cpanel fresh, i already few times installing cpanel before
this is the first time i get this error, when trying restarting apache in whm, after editing PHP Configuration Editor in whm :
Apache restart failed. Unable to load pid from pid file and no httpd process found in process list.
If apache restart reported success but it failed soon after, it may be caused by oddities with mod_ssl.
You should run /usr/local/cpanel/scripts/ssl_crt_status as part of your troubleshooting process. Pass it --help for more details.
Also be sure to examine apache's various log files.
Apache Restart Output:

Hello :)

Do you continue to experience the same issue when rebuilding Apache via EasyApache with those options enabled?

Thank you.
