Hi, hika works fine, i create many categories and products, but today i create some products for category samsung/samsung s4/ and products not appear, redirige to principal category list... (products appear in the back end at his category).

i create a megamenu in top, and directly put links redirecting to the category, you can navegate it, but i create products in s3 and s4 categories and not show, only redirect to principal categories again.

ok, i have names like Samsung S2/SII (i9100) in categories, maybe problem with () or / caracters.... i rename categories to Samsung S2 only and links works fine thanx!!

Thanks for your feedback .
