Why do I get an error message that says "A problem occured... changes NOT saved." when I try to commit changes on my eDoc template?

This error message often happens when you have failed to assign any fonts to the template.  To fix this issue:
1)  Go to the Assets tab of the template.  
2)  Expand the "Fonts" section.  
3)  Select at least one font.
4)  Click the "Save font Options" button.
5)  Go to the Field Setup tab.
6)  Click the "Commit Changes" button.
