    function scene:enterScene(event)                      --print ("post to facebook")                 \_W = -29;         storyboard.purgeScene("restart")         restartbutton2:addEventListener("touch", start2)         keeping\_score = false         function onLoginSuccess()     -- Upload 'corona.png' to current user's account          attachment = {            message = "I have achieved ".. score .. " points playing Helicopter BOB.... download for FREE iPhone & Android at www.site",             source = { baseDir=system.ResourceDirectory, filename="corona.png", type="image" }         }         facebook.request( "me/photos", "POST", attachment )         facebook.request( "me/feed", "POST", {message = "I have achieved (".. score .. ") points, playing Helicopter BOB... download for FREE iPhone & Android at www.site"} )     end           -- facebook listener     function fbListener( event )         if event.isError then             native.showAlert( "ERROR", event.response, { "OK" } )         else             if event.type == "session" and event.phase == "login" then                 -- login was a success; call function                 onLoginSuccess()                          elseif event.type == "request" then                 -- this block is executed upon successful facebook.request() call                       native.showAlert( "Success", "Your Score has been uploaded.", { "OK" } )             end         end     end           -- photo uploading requires the "publish\_stream" permission     facebook.login( fbAppID, fbListener, { "publish\_stream" } )              end  

Any idee what is can be ? ps this code was working before  (mac corona 2013.1137)
