Hi we just installed CU3 update in our SharePoint server https://www.microsoft.com/en-us/download/details.aspx?id=50043 then after restarting the machine the Workflow Manager Backend cannot be started.
I got this error in event logs:
The Workflow Manager backend failed to start at location 'WorkflowServiceBackendHost.OnServiceStarted' due to an exception: System.InvalidOperationException: The current version of the Workflow Resource Management Store, 22.214.171.124, is older than the running product which is designed for the Workflow Resource Management Store version 126.96.36.199. Please upgrade the Workflow Resource Management Store. at Microsoft.Workflow.Common.AsyncResult.End[TAsyncResult](IAsyncResult result) at Microsoft.Workflow.Service.WorkflowServiceBackendHost.OnStartCompleted(IAsyncResult result)
We already tried to restart the service in power shell or in services.exe but nothing works. :(
Is there anything that we need to check to fix this issue?
