If you upgraded to WordPress 3.7 you may find your Shopp storefront has suddenly disappeared. Don’t panic, there’s a simple solution!

Add this code to your active theme’s functions.php file

// Shopp Plugin Fix for WP 3.7
add_action('shopp_storefront_init', 'shopp_storefront_wp37_compat');

function shopp_storefront_wp37_compat() {
add_filter('archive_template', array(ShoppStorefront(), 'pages'));
}

 
Refresh. All fixed? Yay!
