Hi - has anyone encountered and resolved this before. My workflow vanished from the workflow gallery this morning. It was there and working until yesterday. I don't see any support for this online. Please help.
Wow, that behavior I've observed that by my system yet.
Can you see the workflows by using the SharePoint designer ?
Just connect to the Site and click on Workflows, here you should see all your workflow on the Site-Collection plus the Workflows provided by Nintex.
Nope, I already tried viewing it in SharePoint Designer with no luck. It's a good thing I have a back up of it elsewhere, so I just recreated the workflow using a different workflow name.
But If you have to use a different workflow name, the old workflow should be still in place , even you couldn't see the workflow.
So I would contact the Nintex support, to help you.
PS: It is always a good idea to backup the workflows
