Moving from Prefork to Event

[dstana]

I'm wanting to change MPM on one of my servers from Prefork to Event. After making the change in Apache, anything running PHP throws 500 errors. After looking through /var/log/apache2/error_log it seems to be a permissions issue. Here's a WordPress example:

AH01215: PHP Warning:  require_once(/home/xxx/public_html/wp-config.php): failed to open stream: Permission denied in /home/xxx/public_html/wp-load.php on line 37: /usr/local/cpanel/cgi-sys/ea-php74

[cgi:error] [pid 11931] [client 72.216.179.104:65491] AH01215: PHP Fatal error:  require_once(): Failed opening required '/home/xxx/public_html/wp-config.php' (include_path='.:/opt/cpanel/ea-php74/root/usr/share/pear') in /home/xxx/public_html/wp-load.php on line 37: /usr/local/cpanel/cgi-sys/ea-php74

Do have have to update ownership of the public_html folders for all the users? Moving it back to Prefork, everything works again as expected.

Make sure you have mod_suexec installed on the server.

Make you you have mod_suexec installed on the server.

This was it, can't believe I missed that.

Thank you.

Thanks @andrew.n!

@dstana even I did this recently, not a hard one to miss.
