Vhost and Changing public_html to public

Hi, I recently change in Vhost configuration for one domain. Adn the problem is there is lots of script outside (and should be remain that way), i setup subdomain for that folder (public) and worked, tested... etc works fine.  Now is a problem, script is build for working directory public not public_html.
In /usr/local/apache/conf.d/vhosts.conf  folder structure for DocumentRoot, from "/home/user/public_html" to "/home/user/public".

Now domain don't open new public directory instead open old.

How to solve the problem???

Try changing it in Apache Vhosts template
