On my website parmalinks work great but when I click on the categories from the home page it shows them (categories) as /search/category,8/sShowAs,gallery. how to solve it?

@Kamran
First explain what is problem

problem is that when i write the permalink manually on the search bar for example: website.com/vehicles/car/bmw it works but when i click to that category on the categories section of the home page it shows that category as: website.com/search/category,63/sShowAs,gallery.

Ok, it is friendly url as well.

yes but I want to make it the same when I click on the categories from the homepage I want to show the links like website.com/vehicles/car/bmw not like website.com/search/category,63/sShowAs,gallery. People will confuse when they will want to copy the link

Link contains all required parameters, you cannot remove them. It's generated by osclass core.
