Mosaic empty

[Tokatubs]

Hi

Have an issue, when going into the Mosaic editor it is empty. 
Mosaic cloud local shows normal. But when opening editor page it is empty. 

Is there something i can try to reset the editor. Tried both Chrome and Firefox. Both shows empty.

Check for any JavaScript errors in browser dev console (F12)
