The problem is with the theme's CSS file (themes/wpClassifieds/style.css). Or, rather, the problem is that you are not using the theme the way the designer intended — you have the description text in an area that was designed to contain the breadcrumb navigation, which should never spill onto a second line, let alone more than that.
Go to the file I've pointed to, and find the line that says:
Code:
.breadcrumb {background: #EAF6E5;font-size: 11px;margin: 0px 0px 0px 0px;padding: 5px 10px 5px 10px;-moz-border-radius: 3px;-khtml-border-radius: 3px;-webkit-border-radius: 3px;height:20px;}
Replace it with:
Code:
.breadcrumb {background: #EAF6E5;font-size: 11px;margin: 0px 0px 0px 0px;padding: 5px 10px 5px 10px;-moz-border-radius: 3px;-khtml-border-radius: 3px;-webkit-border-radius: 3px; border-radius: 3px;}
The height setting is what's preventing the div from growing (and since there is padding around the text content, it's not necessary at all).
The theme is an older one, going by the CSS file; most of the vendor-prefixed stuff (-moz-whatever, -khtml-whatever, -webkit-whatever) hasn't been necessary for at least three years, and there are no standard (non-prefixed) values.
