I've followed the instructions here on how to configure wildcard subdomains for my multisite setup on Plesk but can't quite get it to work. Everything functions as it should in the backend: I can create a new site and it get's added correctly to the database, but I can't access the admin area. If I visit the home page for the new site I get the Parallels default holding page but the site admin returns a 404.
Can anyone recommend how I might test to find out at which point my setup is not configured correctly? Here's step by step the procedure I've followed.
Set the Domain wildcard subdomains in Apache /var/www/vhosts/domain.com/conf/vhost.conf Add a single line - ServerAlias *.yourdomain.com - to the start of the file. Save the vhost.conf file and restart Apache
Create wildcard CNAME record in DNS for domain using *.example.com CNAME example.com as the parameters rebuild the vhosts config using
Log into your site, go to the home site Administration Panel - Settings - Permalinks - and save them again
NB: Although the linked article talks about retaining webmail for the additional sites this is not a requirement of my setup.
I know a (very) little command line so please be gentle.
