Please help. As soon as I network activate, I get a dreaded Redirect Loop error, and I have to delete the domain_mapping.php file to get it to go away.
I am running WP 3.1.3 with multisite enabled, just two subdomain sites, both working and browsable. I have sunrise.php in place, the sunrise defined in wp-config.php, and I verified that it does create the two domain_mapping* tables in the DB, both empty. I've tried dropping both tables and reloading the plug-in fresh, no luck. I've tried removing the multisite redirect lines in .htaccess, no effect. I've tried going through the plug-in code itself, comment out lines, etc but no luck.
I'd once love to even see the menu itself. Help!
