I have a multisite setup where I have a mix of custom domains and subdomains of the primary site.
The majority of my custom domains automatically redirect from www
to non www
but I have one client that wants it to work the other way, i.e. you type somedomain.com
and it redirects to to www.somedomain.com
.
I've tried the mu-domain-mapping plugin which made me remove the COOKIE_DOMAIN
constant, removing that prevented custom domains being able to log in (they got a cookies not enabled error).
Is there a way to do this natively in WordPress multisite?
