On a single Site Collection, the UI for Nintex 2010 Workflow Manager seems to be broken. On any list, I can click Create a Workflow in Nintex Workflow, but that's about it. The Select a Workflow Template screen's text is jumbled (all the text is bunched up in the upper left hand corner), but I can proceed by clicking on Create.
Once in the Workflow Manager UI, I am unable to drag and drop Workflow Action objects onto the workflow. I am unable to save, close or really do anything. None of the Nintex buttons work. Workflow Settings does pop open, but it won't save any changes, the form just stays open like the save button wasn't clicked.
To troubleshoot, I have removed and re-added the Nintex Workflow Feature from the site-collection, but that didn't help. It's like Nintex needs to be reinstalled/repaired on this Site Collection. It works fine on every other site collection in the web application. Any ideas on what I can look for?
Thanks in advance for any help.
EDIT: Can someone please move this to the 2010 forum?
