Made a whiteboard, put in an image some sticky notes and arrows. clicked on save. save button stuck on "saving". refresh - everything gone - okay refresh again, still gone. redo the content on the whiteboard, wait for "saving" to change to saved or whatever. Doesn't happen and after pressing the button, and refreshing it, the content is gone again.

Even when i have nothing on the page it is still stuck on Saving..

see description.
