Hi - when I try to activate this on one particular blog in our Multi-Site install, this is the error I get:
Fatal error: Cannot redeclare um_kses_init() (previously declared in C:\wamp\www\wp-content\mu-plugins\unfiltered-mu.php:28) in C:\wamp\www\wp-content\plugins\unfiltered-mu\unfiltered-mu.php on line 30
Not sure if this is just an incompatibility with WP 3.0.1 - we haven't yet upgraded for a variety of reasons, so that could be the problem. Thanks in advance for the help.
I see previous thread having difficulty with this too... wondering if it's the same issue?
