@duncanc thanks for clearifing the query argument “id” usage.
also, im using a local server for development. (and the same server also serve the ajax enable form you provided.)
so, i guess ACCESS_CONTROL_ALLOW_ORIGIN is out of the question (though i even tried define("ACCESS_CONTROL_ALLOW_ORIGIN", "*"); in config for testing)
still the localhost server return “FAIL” output.
p=asubscribe&id=1 and request email=aaa%40aaa.com&attribute1=aaa&htmlemail=1&list%5B3%5D=signup&subscribe=subscribe&VerificationCodeX=
where my subscribe page id (default page) is 1
and list-id is 3
