On my home page, the "Top Posts" banner shows a thumbnail, then the post title.

After the title, the post text is showing for some reason. I only want the title to show on the home page, without the first word or two of the article.

What do I need to do to fix this?

I attached a screenshot.

Dear Daniel,

That is the post previous, which is being displayed by default. You can hide it by adding this code to the style.css file of the theme:
If you'll need the previews back, just simply remove that code.
Thank you.
