Hi!
The reason for this problem is styles of your third-party plugin WP Properties which overlap our styles. We may suggest you the following solution - replace the line:

.container { width: 1000px; margin: 0px auto;}

with:

.container { width: 1000px; margin: 0px auto; display: block;}

inside the css/wide.css file located in the directory of the theme.
