Picture opens with black background and must use browser "go back one page”
I have WordPress, Woocommerce and Wootique installed. When I click on a product picture the picture opens but the background is all black and there is no way to click on some x to shut down the picture. The only way I can see my website again is to click on the arrow “go back one page” on the browser. Does anybody know why I got this problem and how I can solve it?
When I use the theme Mystile it works without any problem. But I want the Wootique theme because I like it more.
WooCommerce version 18.104.22.168
WordPress version WP 3.4.2
AWD Weight/Country Shipping by Andy_P version 1.0,
WordPress SEO by Joost de Valk version 22.214.171.124
Wootique 1.4.1 Framework 5.4.1
PHP Version 5.3.18
Thanks for all help in advance.
