Error - Accessing Data Failed
I'm trying to updated attributes in a hosted feature service and am getting an Accessing Data Failed message. I can click in the attribute field and make a change but when i hit enter it wont save the change and the error message appears.
I have tried
1. I have editing enabled on the feature service but have only certain feature classes with editing enabled on a web map. The feature classes with editing enabled in the web map I can edit but not the feature classes without (even after I enable it).
2. I have opened the feature service in a new map with full editing enable and the error message appears.
3. I have opened from my Arc Map desktop also and get the following messages 
Can somebody provide m with some suggestions I figure I have not turned something on/off somewhere? I don't want to overwrite/append my feature service if I can help it.
Thanks
Sandi
