This server is very old but runs Centos6, php 5.6.39, mysql 5.6, etc. Assuming, it's safe to ignore all the php4 messages, why are those even listed? Not sure tbh... I have php-fpm service for cpanel daemons disabled in service manager. Does this enable the old cpphp? Think I'm still using that... should I enable the php-fpm service for cpanel daemons? I'm using the bluehost symlinkprotection patch...on a VPS, don't control the kernel, any other possibility for marginal symlink protection outside of cloudlinux, kernelcare, or moving hosting providers? What about these? cpphpopts? systimezone? expat? safephpcgi? access? Fileprotect is already enabled in tweak settings so think that is covered. Thank you.
