I have a subdomain WP multisite network with domain mapping
one of the domains is expiring. I want to 301 redirect the domain back to the multisite subdomain and keep those pages active.
I don't really care about individual pages, just redirect the whole thing to one address
I have the WP Redirection plugin installed but everything I've tried results in a loop so looking for an htaccess solution - but no clue about how to write that.
