We just upgraded our site from 4.5.0 to 4.7.1. The site works fine, but we can't get any of the nodes under or main content node in the backend.
I used firebug to figure out the script error and found the page that it's trying to hit and the error. Does anyone know how to fix this or what I might try?

Fixed. Some of the nodes had a user that was deleted. I changed the userIDs on those nodes to the ones there were in umbraco and it worked.
Thanks, you just solved my problem :)
