My app has been live on Smugmug for many months. While testing other changes for iOS6 (unrelated to Smugmug api code) I did a test upload. The image was not uploaded & the result which came back was:- code = 5 system error method = "smugmug.images.upload" stat = fail
The code has been working for some time & is untouched. I can't see anything wrong with my code so I wondered if there had been any API change that's not obvious to me in the past few months. My app is logged in via OAuth & can view albums on Smugmug.
