How to make a best seller page prestashop 1.6

[Crazyweb]

Hi 

 

I have asked this question before, but never had any reply.

 

Is there any one who know's how make a best seller page ranked like the best sellers blok.

 

Now if you install prestashop it will link you to a best sellers page, but the sold products are just random.

 

For sure all prestashop 1.6 users have noticed this, but is there any one with a solution.
