WPMU places restrictions on certain tags like [embed] and [object].
Try installing the Unfiltered MU plugin and then attempt to embed your SWF.
Hmm installed unfiltered, but I don’t see options anywhere for it? It doesn’t show up after activating that I can see.
There are no options for the Unfiltered MU plugin.
Try to embed your SWF in the Text/HTML widget now and tell us what happens.
It didn’t work, so I scrapped the swf banner idea and went with a jpg instead. Perhaps I’ll revisit it a little later down the road.
Just trying to get my site up and as function as possible as we just went live w/ open beta a few days ago .
