Error while adding Apache directive to Vhost

I have created a Apache directive in ISPCONFIG. When I tried to add the same to website, it returns the error like this:

Code:

apache_directive_blocked_error
Include /etc/apache2/custom.d/globalblacklist.conf

the directive I am trying to add is like this:

Code:

<Location "/">
Include /etc/apache2/custom.d/globalblacklist.conf
</Location>

but If I add the same directive to /etc/apache2/sites-available/thedomain.tld.vhost - manually without ISPCOFNIG interface it works fine without any issue.

 

Thanks. I didn't knew that.
