Hi after a long time, today I came here to post a problem that recently happened in one of our customers, so I will put you on situation:
We have a Sharepoint farm of 1 Front End, this farm is fully patched until CU December ’14, and we have installed in the Farm the Workflow farm. We were deploying the portal until an error came across after one of my colleagues tried to manually start a Workflow and receive the following error:
Lo sentimos, se ha producido un problema
Method ‘StartWorkflowOnListItem’ in type ‘Microsoft.Sharepoint.WorkflowServices.FabricWorkflowInstanceProvider’ from assembly ‘Microsoft.sharepoint.WorkflowServices’, Version=126.96.36.199, culture=neutral, PublicKeyToken=71e9bce111e9429c’ does not have an implementation.
After some digging on Google, I realized that the root of this problem could be a bug, so we found that when we upgradeSharepoint Server, STS services does not updated properly and require a separate update, and there is a mismatch of STS and Sharepoint wchich cause this issue.
To solve the problem, we need to install the following security update “Update 2880963 for SharePoint Server 2013: May 13, 2014”. http://support.microsoft.com/kb/2880963
Yes, you’re Reading right, a May ’14 update when I have the farm patched until CU December ’14, weird isn’t it?
I have to add, that I have installed the security update and it solved all the problems that we were having on this farm. So… go on!
Another piece of information: There is no need to restar the server after the update has been installed, try to start the WF once again and good luck.
