Error 404 with my url format

[njcalvo]

Hi, i want to put the next url format for products:

{rewrite}-{id}{-:id_product_attribute}.html

Others url formats are the originals.

I receive 404 error on some products. If I put {rewrite}_{id}{-:id_product_attribute}.html, {rewrite}-{id}{_:id_product_attribute}.html or {rewrite}-{id}0{-:id_product_attribute}.html or something similar I dont receive any error.

Anyone can help me?

Thanks

What's your prestashop version? I don't think that's possible to be honest, id_product_attribute is not an available element for urls

I use the last version (1.7.5.1)

I cant save if I dont use {id_product_attribute} on product url, it's a required field.

The prestashop installation is new, i dont installed anything.
