After upgrading to v1.2 I can no longer access the Settings → Sharing menu (Jetpack's implementation of ShareDaddy). It's disappeared altogether from the sidebar; I can click the link in JetPack → Sharing, Learn More but it gives me the error message "You do not have sufficient permissions to access this page."
Any suggestions? I've tried restarting Apache to clear any opcode caches, emptying any WordPress caching plugins, checking that permissions are all correct, looking at the logs for any PHP errors, but no luck at all. Any help would be appreciated.
