Just an option, but I built a CMS system[1] that actually generates static websites that comes with options for WYSIWYG or markdown. It's node powered, but if you're a php coder it might not be what you want, but we do use the Swig template language (based off twig, based off django...etc). The biggest thing really is that it stores all it's data in a firebase, so the actual CMS is realtime even if the website is compiled staticly.
We're launching later this week, but I can sneak you in early if you'd like. Just send an email to dave@webhook.com
