 * Hi, the plugins seems to be exactly what I am looking for however I have encountered
   on various errors:
 *  1. “Function wpdb::prepare was incorrectly used”… it says that it is not using
   placeholders as it should be but concatenating strings.
 * 2. apply_filters( ‘site_url’, $url, $path, $orig_scheme, $blog_id ); causes problem
   as no variable from this expression is defined.
 * Thanks for your time.

 * Well, the errors are just not visible…
    With “define(‘WP_DEBUG’, true);” I get:
 *  – ( ! ) Notice: Undefined variable: url in <path>/wordpress/wp-content/plugins/
   fma-product-custom-options/admin/class-fme-product-custom-options-admin.php on
   line 13
 * – Notice: Funkce wpdb::prepare **nebyla použita správným způsobem**. Při použití
   funkce wpdb::prepare() musí parametr query obsahovat nějaký zástupný znak. Please

 * Did you manage to fix the errors? My cart doesn’t even work when the plugin is
   active. Could the errors be the cause of it.
