There is an error in generating vhost in the mod_security2 section. This section is inside other section (mod_dav) and not work. After manual repair, everything works until the ISP regenerates vhost. Adding screeenshot:
I need to change SecRuleRemoveById on some sites. I have to remove the entire section from the mod_dav section and put it separately above it. But if I make some changes to the domain, the vhost will regenerate and it is wrong again.
search th forum for custom vhost or customize vhost, you will find plenty of threads like this one: https://www.howtoforge.com/community/threads/customize-template-for-vhost.65253/
