I couldn't reproduce the error with the save settings on my localhost and for some reason I can't upload files with the FTP information you provided, so I can't debug your live files.
I did manage to fix the issue on the users and activity pages. Please try replacing your files with the new .zip file I just uploaded. If you still have issues with the save settings then I'll need to do screen sharing to reproduce and debug it with you since I can't seem to get the FTP working correctly.
