Problems uploading to App Store

Question

Hoping someone can help me here as this is driving me insane. I used to have no issues uploadeding to app store.... until i updated xcode to v4.

I have tried deleting all certificates, provisioning profiles etc and startng again but that doesnt work. I have checked that the builds are using the right profiles etc but that still bring up the following message as a yellow fault indicator (so still managed to build succesfully, just doesnt allow me to upload!)

Hopefully someone can help?

Answer 1

Fixed.

Nothing wrong with my coding - this was a certificate issue at Apple's end and that has been cleared up now.

To fix - delete all certificates and keys relating to your development and distribution profile, and mobile provisioning. Revoke certificates on the provisioning website and reapply for all.

This fixed mine, now no issues and app submitted fine!!
