How can I make sure that the page is not set in header or footer template?

The website is called escturkey.com and is currently on maintenance mode.
When I add something to a page, then it appears at the bottom of the home page.
Also when I add something to a page, it appears on different pages as well, not only on home page.

This is how the home page looks like:

<script async src=”//s.imgur.com/min/embed.js” charset=”utf-8″></script>
