Just upgraded to WP 3.1 and the development version of wordpress-mu-domain-mapping.
I have Permanent redirect checked but domains are not redirecting to their primary domains like they did with 3.0/0.5.3. Example: http://iccreatives.com/ was redirecting to http://icreatives.us/, and now it's not. Also when on the non-primary site it looks like all of the resources and links are coming from the non-mapped domain.
Any ideas on when an officially 3.1 compatible release will be available or hints on how to fix this behavior?
Thanks for the great plugin.
