Disable Mod Security cPanel for a domain

1 – Create directory at :-

[root ~]# mkdir -p /usr/local/apache/conf/userdata/std/2_4/username*/domain.com*

2 – Then create a file in it :-

[root ~]# touch /usr/local/apache/conf/userdata/std/2_4/username*/domain.com*/mod_security.conf

3 – Edit the file and add below line :-

[root ~]# vi /usr/local/apache/conf/userdata/std/2_4/username*/domain.com*/mod_security.conf

===cut===
SecRuleEngine Off
===cut===

4 – Then run this command to allow httpd.conf to include the file.

[root~]# /scripts/ensure_vhost_includes --user=username*

And if you want to remove the mod security, just remove the line.
