Added a page and it's blank or no response

I added a page and this works - 

```
---
{
   "template": "templates/page.html",
   "page.title": "Test"
}
---
## This is a test
```
This does not -

```
---
{
   "template": "templates/page.html",
   "page.title": "Test"
}
---
This is a test
--------------
```

Can you see why? Marked.js does not seem to like it for some reason.
