Subdomain Prerequisites

To enable subdomains on your website, you must first configure the following 5 items. If something isn't working, refer to the suggested solutions and make sure you have completed each step outlined in readme.txt.

DNS server - show/hide details Not working yet
test-1.template-247.com failed to resolve
test-2.template-247.com failed to resolve
test-3.template-247.com failed to resolve

It appears your DNS server is not setup to handle wildcard subdomains (*.template-247.com) for template-247.com. Edit the DNS zone file or settings for your server to fix.

PHP caches DNS lookups, so you'll want to restart your web server after making changes to your DNS server to see the results of your changes on this page.

CONFIGURING APACHE
===========================================================
STEP 1: Edit httpd.conf, enable mod_rewrite and configure
wildcard virtual hosts. An example configuration that you
can append to your httpd.conf is below. Replace the domain
name and directory as appropriate, save, and restart apache.

NameVirtualHost *:80
<VirtualHost *:80>
    ServerAdmin webmaster@example.com
    DocumentRoot /var/www/html
    ServerName example.com
    ServerAlias *.example.com
 
    <Directory "/var/www/html">
      AllowOverride All
    </Directory>
</VirtualHost>
