Child Theme not working

Can you please include a link to your site when you post a question? It makes it easier to see what might be wrong. Thanks.

However I’ve deactivated the child theme atm.

Can’t say for sure without looking at the site with the child theme activated whether or not your CSS files are being loaded. You should be able to tell, though. Once you activate your child theme, if you look at the page source, you should see a couple of lines that look like this:

<link rel='stylesheet' id='parent-style-css'  href='https://www.megschildren.org//wp-content/themes/twentyfourteen/style.css?ver=4.1' type='text/css' media='all' />
<link rel='stylesheet' id='child-style-css'  href='https://www.megschildren.org//wp-content/themes/twentyfourteen-child/style.css?ver=4.1' type='text/css' media='all' />

There’s an easier way of hiding the “Proudly powered by WordPress” footer, though. Just add this CSS rule to your custom CSS:

.site-info {
   display: none;
}

Yes it’s including the stylesheets…

Your child theme stylesheet looks OK, so hard to say why your header image wouldn’t appear. Are there any other files that you copied over/created in your child theme, like a copy of your header.php file?
