Hi,
That code should work 100% .You have syntax mistake in your custom css so thats not working . Please go to Admin -> Theme Options -> General Options -> Custom CSS -> Here find all css code
#header {
background: url(http://shop.garsons.co.uk/wp-content/uploads/2014/05/Header-01.
.product_list_widget span.product-cats {
display: none!important;
}
Change with this correct code
#header {background: url(http://shop.garsons.co.uk/wp-content/uploads/2014/05/Header-01.png)}
.product_list_widget span.product-cats {display: none!important;}
Hopefully that should work 100% and let me know your feedback. Thanks Melanie :-).
With Best Regards
