I've been doing reading about setting up MU to handle blogs with their own sub-subdomain (as in the topic title of this post). The closest thread I found to what I'm trying to do is http://mu.wordpress.org/forums/topic.php?id=5192 but that person is actually trying to do the opposite of what I'm trying to do (change blogname.blogs.domain.tld to blogname.domain.tld).
Believe it or not, I actually want to do the opposite, having blogname.blogs.domain.tld. Here's the problem.
When I first installed MU, the domain scheme was "wordpressmu.domain1.tld" with individual blogs being created as "blogname.wordpressmu.domain1.tld". Then, we decided to change it to "blogs.domain2.tld" with individual blogs still being created as "blogname.blogs.domain2.tld".
All of that worked, except now when I go to the wp-login.php page and sign in, I get the dreaded "WordPress requires Cookies but your browser does not support them or they are blocked." error.
I've tried editing the wp-login.php file in as many ways as are mentioned in the different threads on the subject in the forums, but to no avail. I still get the error and can't log into the admin console of the blog server.
What am I missing? Can I really do what I'm trying to do? Did changing domain schemes midstream mess me up and if so, how do I fix it?
Thanks.
