Upgraded jigoshop and it stopped working.

in functions.jigoshop.php on line 11 change this:

remove_action( 'jigoshop_before_single_product_summary', 'jigoshop_show_product_sale_flash', 10, 2);

to this:

remove_action( 'jigoshop_before_single_product_summary_thumbnails', 'jigoshop_show_product_sale_flash', 10, 2);

In header.php on line 85 cut this line of code out:

<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" />

and add it down down near line 144 just before </head> like this:

<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" /> 
</head>

Go through the new jigoshop settings and click “Save” again – this seems to help the upgrade process.
