Hello,
I have a strange problem with the media player block rendering embeded video files.
It seems the player graphics are not loaded correctly and an empty iterface is loaded.
I tried to find a jquery conflict but it seems not to be the reason of this strange rendering.
I have the same behaviour on backend and frontend.
I have tried with different files and filestypes and i have the same result.
Please can you check the example on this test site url (copy of the production site with the same problem) to find the problem.
Cordialy,
