Bugs with sorting bar

[BlackAlpha]

Hello,

 

I started with PrestaShop and try to understand the different aspects.

I installed a module that allows the shop to be on "catalog mode" for visitors and display prices and the possibility to order only to registered customers.

 

I have two problems (which are more or less related):

- In catalog mode, prices are marked as "undefined" 

- When I change the display format and I pressed repeatedly on one of the formats, the list shows only "undefined"   (see attached file)

 

I don't know if sorting is a module or whatever, but I can't find solutions, or people who have encountered the same problem.

 

Do you have any solutions for this ? Thank you 

 

(sorry for my bad english, I'm french)

Can we see it online? What module are you using?

Thanks for your reply
Unfortunately the website is currently offline, i don't have any module for sorting my product, it seems to be an included-module that's why I can't find how to resolve. I think it's a default sorting bar with Prestashop (1.6)
