Hello, cPanel Security Advisor suggest me to Enable "Jail Apache" in the "Tweak Settings" area. I go to Tweak Settings, but i can't change and set to "on". Can you help me?

  Hi @thanasis, Is mod_ruid installed? Clicking the [?] next to the tweak setting we have the following: [QUOTE] EXPERIMENTAL: Jail Apache Virtual Hosts using mod_ruid2 and cPanel" jailshell. [?] If mod_ruid2 is compiled in via EasyApache, mod_ruid2 is enabled, and a user has their shell set to jailshell or noshell, enabling this option will chroot() a user's Apache Virtual Host into the cPanel" jailshell environment. Each user will require 14 bind mounts. While modern Linux supports a very large number of bind mounts, many processes read /proc/mounts (even mkdir on RHEL 5 and CentOS 5). Reading /proc/mounts can be quite expensive when it becomes large. We strongly recommend that you do not exceed 256 jailed users unless you use RHEL, CentOS, or CloudLinux" 6 or higher.
  When I remove mod_ruid, I can see this tweak setting is greyed out. Thanks,
