XF 1.3 Facebook intergation fails to work XF v 1.3.3

i get this error when i test the integration: Facebook returned the following error: The request is invalid because the app is configured as a desktop app.
ok nm fixed it had to re create the app but its a shame i had to disable this function as well

App Secret Proof for Server API calls App must submit a proof of app secret

and this function that gave me the 1st error:
Native or desktop app? Enable if your app is a native or desktop app

turning that off fixed it.
