vrijnatuurlijk

I’m having the same problem, tried switching between thickbox and shadowbox, nothing helps, the video stays broken. All are the latest versions.

For screenshot: https://vrij-natuurlijk.nl/wp-content/uploads/2010/11/screenshot-ytsg.jpg

I am using the dynamic header plugin on WP 3.01 and twentytenweaver. However when I try to change a header on a page, it doubles the header as you can see here:https://natuurtalent.eu.greenhost.nl/bedrijven/

I removed all snippets from 2010 advanced.

How to solve this?
As I am on a deadline with this one, help would be very much appreciated!
