I have a blog with multiple authors, and since I upgraded from 2.7 from 2.3 a few weeks ago, my contributing authors are unable to embed videos into their posts. When they click "Publish" or "Save Draft", the embed code DISAPPEARS. It is completely stripped from the post.
This happens with video code from any source (YouTube, Metacafe, Dailymotion, Break.com -- you name it.)
The funny thing is that I, as the Admin user, am able to post videos or other embedded content just fine.
All of my other contributors have "Author" permissions. This happens whether or not the "Disable Visual Editor" box is clicked in the user settings.
Anyone have any ideas or suggestions?
