I've had a VIMEO embedded via the "Featured media" widget on one of my pages and it has been working fine for a year.
Now I tried to use another video by entering a new URL for my new VIMEO-video, but it stopped working and the space only shows a blank space with the widget text over it (ref: http://modenatt.se/modenatt-videos/).
No other changes made when problem started.
Now I've tried embed other videos from VIMEO without any success and also tried to first delete then start over with a new entry and video, nut without any success.
Any suggestions on what might be the problem?
