title: Facebook Error: "The client token cannot be used for this API" - works on DEV and STAGE but not on LIVE app?
body: <p>I've built a notification sending system that sends notifications to all users of our app, using the app access token.  This system is currently running on my localhost.  When I configure it with the appid and appsecret for my dev and stage environments, it works fine.  But when I put in the appid and appsecret of the LIVE app, I get this error:</p>
  
  <p>{"message":"The client token cannot be used for this API", "type":"OAuthException", "code":190}</p>
  
  <p>So what's different between dev and live?  Dev and Stage are in sandbox mode, Live is not.  So I tried disabling sandbox mode on Dev/Stage and they continue to function fine.  Dev works fine, Stage works fine, Live gives this error.  All other code is the same except for the appid, appsecret, and redirect_uri (changing it to match the domain of each environment). </p>
  
  <p>I have checked <a href="https://stackoverflow.com/questions/13188571/error-the-client-token-cannot-be-used-for-this-api">this</a> post, but unfortunately resetting our appsecret on a site with 1,000,000 users is not something we can do at the moment (too much other functionality relies on it).</p>
