Symptoms
After saving a workflow that was created from our SharePoint list, when trying to open it back up for edit, the customer gets an error:
>XML_MissingRoot]
Arguments:
Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://www.microsoft.com/getsilverlight/DllResourceIDs/Default.aspx?Version=5.1.41212.00andFile=System.xml.dllandkey=xml_missingroot
Diagnoses
The customer cleared their cache and tried opening the workflow in different browsers. Labs offered a link to attempt to find out from where they were hitting the error if coming from the web service call.
Resolution
Resolution: Customer opted to start the workflow over from scratch.
