Hi,
Okay I see the problem.
HikaShop does not add any "p" in the database but HikaShop refuse that a product name start with a number when it has to SEF it.
When a product start with a number in the url, it's to give the product id ; so if the product start with a number, it will confuse HikaShop which won't be able to display the right product (because it will think it's an id)
That's why HikaShop add a "p" as prefix when creating the SEF urls.
