We have an iOS app in the app store using the addthis sdk for sharing an image to facebook and twitter.
In testing (before and after release to the app store), it was working great.
However many users are reporting a uialert saying "Error - An internal error occurred" when attempting to share an image (I get this message on my device now too).
The code has not changed. Any idea why this might be happening? Is the addThis sdk having issues with iOS5 or some version of iOS.
