I've just setup a twitter account for our website and when clicking on Actions -> Run under the Feeds & Nofitications page I get a popup saying
"Could not load file or assembly 'Newtonsoft.Json, Version=184.108.40.206, Culture=neutral, PublicKey=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"
Any ideas on how to fix this? If it comes to it I will open a support ticket but just wondered if anyone else had hit this problem.
