Can you copy the content-home.php file from the Spun theme and paste it into your Child Theme directory?

That’s what you do in a Child Theme by the way; every time you want to modify a PHP file other than funcitons.php you copy it from the parent theme and paste it into the Child Theme directory.

Done this already

Wait, when did you do this?

Okay, I thought you meant you did it a while ago and you had modified that file already. I wanted to make sure the changes I was about to recommend would have worked to your file.

Carrying on, try replacing all of the code from your content-home.php file (of your Child Theme) with the code from this PasteBin page: http://pastebin.com/e40FLjei

Does anything happen on the homepage of your website?

Can you link your website?

Try removing your ‘overflow: hidden;‘ style in your Child Theme style.css file, here:

.hentry.no-thumbnail {
 ...
	overflow: hidden;
}

When there is more than one row of circles (or squares in your case) this extra word will be overlapped, you can explore this by resizing your browser to a smaller size.

To resolve this you could add the following CSS:

.home .hentry { margin-bottom: 30px;}

BTW if you want to get the words centred get rid of your   entities and put this in the CSS:

.home .hentry p { text-align: center; }
