When visiting my edit profile page from stackoverflow and click 'Copy Profile to all Stack Exchange network accounts' without making any changes I receive the following error:
Oops! There was a problem updating your profile: temporary error updating your profile -- please try again!
Reproduced multiple times in
- Chrome 15.0.874.120 m
- FireFox 8.0
After changed - even a single character - It works as expected.
I think it should just do nothing on the back-ground and say it was succesfull - or display an notice that you havn't made any changes.
