I initially posted a question SO
http://stackoverflow.com/questions/18934982/opening-yoast-com-opens-up-my-localhost-dev-serverhttps://stackoverflow.com/questions/18934982/opening-yoast-com-opens-up-my-localhost-dev-server
But it was being flagged as off-topic.
Was I not supposed to do that?
Is this question even off-topic for SF? (it's being downvoted)
