Hi, I'm having problems creating my multisite subdomain network. It works fine in directory install. I've installed it in the root, created my wildcard subdomain and redirected it to the blog domain. I've manually installed the mu-domain-mapping plugin. I created the mu-plugins folder under wp-content - but the moment I add the domain-mapping.php, my blog goes blank. once I remove it, my main blog is again visible, but my subdomain dashboard gives an NOT FOUND error message.
What am I doing wrong?
