A few days ago John Burton contacted me asking if I knew why he couldn’t get Wordpress MU to show embedded YouTube videos and podcasts that he was working with. To tell the truth, I had no idea, but I agreed to check it out with him. He was quicker then I and found an easy way to fix it .
Turns out Wordpress MU filters the code and disables the embed features. How do you fix it?
Edit wp-include/kses.php. In that file search for “Post filtering” and then comment out the following lines:
// Post filtering
//add_filter(’content_save_pre’, ‘wp_filter_post_kses’);
And that’s all there is too it.


I hope WordPress developers replace kses with htmLawed (which is actually developed off kses) and put in place a control panel for setting htmLawed options (tags to filter, etc.). htmLawed seems to be much. much better than kses.
Thanks for your good idea, try it.
my wpmu couldn’t toooo.
