Django Ajax "FORBIDDEN" error

I've seen instances where people are getting forbidden errors while attempting to make remote Ajax requests, but I'm making a local request and I also have CSRF turned on in my middleware.

errorThrown is returning "Forbidden"

I think the issue might be that I'm trying to send this to a normal view (the current page)... I'm not sure if my preprocessor is returning to the view to re-render the page.. or if it's returning right back to my current page. (don't think I explained that very well)

Hopefully this gives you a good enough picture of whats going on. Any/All help is appreciated.

the .ajax:

jQuery.ajax({
        type: "POST",
        dataType: "json",
        data: dataString,
        success: function(json) {
              jQuery(".signup").attr('disabled', false);
              $('.success').show();
              console.log(json.message);
        },
        error: function(jqXHR, textStatus, errorThrown) {
              jQuery(".signup").attr('disabled', false);
              $('.fail').show().append(errorThrown);
              console.log(textStatus);
        }

    });
