If you could make sure that the 'content' section is present in the Page template area of the drag and drop template, and that 'postloop' is present in the Content-area of that template. Both of these are required for the page content to display.
If both of those are present in the drag and drop, go to Pages>find the page you're working on and look at the page meta settings. Check that you've not accidentally set either of the above sections to 'hidden'.
