I'm getting this same error message while uploading the app on store. I've double check the bundle Id of my application, verify the profiles and certificates and also cross check the unique bundle id is used in developer account.
We have already uploaded the app on this account before and its live now. Don't know how this error occures now.
We have to resolve this as soon as possible just because we have an event by last week of this month and before that we need to resolve this issue.
