Version 6 is completely broken. We had AAM on this site for a while. It always worked. Ever since updating it STOPPED protecting pages. I have reset the plugin numerous times and tried to set it up again but it doesn't work. I created a NEW PAGE, selected redirect and I get "Updating failed. Error message: The response is not a valid JSON response." This is on a brand new page which has never had redirect. This plugin is junk.
