In the first post, I discovered that when running workflows in the 2010 platform previous versions may need to be deleted; in the second, I found that the activity cache on your local machine can prevent new versions of your workflow from being published.
This post is related. If a workflow fails to run with the error: something went wrong to try again reload the page and the start the workflow, you may need to restart two services. To do so check the server SharePoint is on and look for the two services:
- Service Bus Gateway
- Service Bus Manager Broker
If either of these services is stopped, restart them and try to rerun your workflow.
