I'm having problems with this combination and cannot let it work locally. I've got the same PlugIn in another local version and online working perfectly though.
Previously - in wp3.1.3 - I also had to modify the path for the local flash movie, e.g. "/flash/flashmovie.swf" online and "flash/flashmovie.swf" locally. Now I went through some variations with and wthout slashes, but it doesn't help ...
Anybody else with similar problems?
