since updating to iOS7 I cannot upload my photos to a shared photostream
working with Mountain Lion and iPhoto: after updating my iPhone to iOS7 suddenly the upload of photos to shared photostreams does not work any longer. I tried all the ways through iPhone, iPad and MBP, but alas to no result: cannot upload photos any longer. Anyone has any suggestions how to solve this?
iPhoto '11, OS X Mountain Lion (10.8.5)
