This is a really strange behavior - it seems that for some reasons the Editor on your page does not access its localization files. I tried to reproduce this issue with the DB content provider from this code library
, but the error message was displayed properly on my test page - screenshot
For my test I have used the latest official release (2013.1.417). I have attached a sample project to this message, could you try it and tell me whether you can reproduce the same behavior with it? If no - could you modify it up to a point where the problem occurs and send it back?
Looking forward to hearing from you,
