Hello
I found a solution for taking off the -detail suffix from product url but its outdated.
Attached is router.php
I am sorry, but that is too outdated. I also wonder how it is solved, because it is a set problem. To use the router without -detail is no problem as long you assure that a product slug is never used as category name or similar.
I am not a php developer i just attached this file becouse i know many people want to remove that suffix.
but as Max says - as soon as you have a cat slug with the same name as a prod slug u have a problem - the product detail is unreachable as it will default to the cat
