Disable DudaMobile and re-enable wptouch. wptouch should work right out of the gate. I've used it for years and it's a very good plugin. I actually purchased the pro version.
All the other mobile builders I tried never worked like I wanted them to or as promised.
EDIT: I would undo whatever dudamobile had you do. I bet they had you create the re-direction and that is what's causing your problems. I can't remember the place you would do that off hand, but I'm betting that's where you problem is. The re-direct is set to go somewhere there are no files; hence the error message.
