Theme Horse

HI Leeann,

Did you customize and code? If not then first of all deactivate all the plugins that you have installed in your dashboard. If the same issue exist Go to Apperance > customize > Ambition Theme Options > custom CSS and paste below CSS Code:

.featured-slider .featured-image {
    min-height: 260px;
}

We have already update above CSS code in our latest version but it seems that it was not loaded in your site.
Hope now this will help.

Thank you!
