I have also a problem working with WordPress 3.
I get the following message: “Audio clip: Adobe Flash Player (version 9 or above) is required to play this audio clip. Download the latest version here. You also need to have JavaScript enabled in your browser.”
But in WordPress < 3 I have no problems. A re-install doesn’t fix the problem and there are no other Plug-Ins running in WP3.
Is there a workaround?
