Sitecore + Social Connected 2.1 + Twitter. System.OverflowException issue with TweetSharp library
You setup Social Connected module and configured your twitter app correctly? Getting authError parameter in the URL and System.OverflowException error in the log file? You’re definitely having an old TweetSharp library that causing this issue. Social Connected 2.1 uses TweetSharp library to communicate to Twitter API and there is a breaking change in twitter with user id that isn't targeted by this version of Social Connected. If you are running on SiteCore 7.2+ platform - you're safe as you can use 3.0 version which addresses the issue. If you're running on Sitecore up to 7.2, then you're in a little trouble, but don't worry too much as you can apply the following fix (at your own risk though :) ) Download Social Connected 3.0 Don't install it! Unpack the package Find TweetSharp.dll in the package and copy it over to your S itecore bin folder Enjoy!
