I have an on premises SharePoint 2013 farm. I setup a host named site collection for a user and made him a site collection administrator. He can see 'Workflow Settings' in the ribbon but its disabled. I then granted him Full Control on the site collection and he still can't see an enabled workflow settings.
We use a branded version of Nintex but from what I've read everything is enabled at the site collection and site level that needs to be for the workflows to be available. In fact, Myself (Site owner and Farm Admin) and the other workflow developers are able to see an enabled workflow settings. Is there a setting in Central Administration that I'm missing?
