I just recently upgraded to WPMU 3.0.1. It has caused some problems with my Supporter plugin, however, I think its minor.
When I click under Super Admin on Supporter it will bring me to the right page with no 404 error-
/wp-admin/ms-admin.php?page=supporter - note it is calling ms-admin
On the modify a blog, setting, premium plugins, and premium themes the code looks like -
/wp-admin/wpmu-admin.php?page=supporter&tab=settings - calling wpmu-admin
I was wondering how to change it from calling wpmu-admin to call ms-admin because that fixes the problem.
Any info would be helpful!
