We have a workflow attached to our SharePoint 2007 site, which is heavily customized and lastly updated almost 3 years ago. It was working well in last few days but during noting down the steps in this workflow, we don't know what went wrong and we ended up with error:
Error retrieving config xml for activity 'startWorkflowActivity1' using adapter type Nintex.Workflow.Activities.Adapters.NWStartWorkflowAdapter, Nintex.Workflow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=913f6bae0ca5ae12.
How we can fix this issue ?
