I installed sentora and added my domain to it. If I accessed any wildcard subdomain it gived me sentora panel. So I edited httpd.conf by adding virtual host which is pointing to subdirectory of my main domain. At that time I was getting Apache testing123 site and I deleted welcome.conf file. Now it should everything work but I always get 403 error probably I made some mistake by editing httpd.conf .
Code:
<Virtualhost *:80>
# ServerAlias *.rh.hr
DocumentRoot /var/sentora/hostdata/zadmin/public_html/rh_hr/subdomains
# DirectoryIndex index.php I
# <Directory /var/sentora/hostdata/zadmin/public_html/rh_hr/subdomains>
# Order allow, deny
# Allow from all
# Require all granted
# </Directory>
</Virtualhost>
