We had to do a restore to a DNN installation that included DMX. We got the site and the DMX module back up and running, but we are getting 404 errors when selecting Add File(s) or Add Folder or edit attributes on existing files. The module simply refreshes back to the main screen. When I check dev tools there are several DMX API calls that are throwing 404 errors. I've re-installed the module and checked permissions, but no luck. Looking for a little help.
