Can't change products sorting [Presta 1.4.4]

[Prestadaube]

I need to update an existing website I didn't develop.

 

There is one issue I can't figure out how to fix:

 

On the online shop, all the products are sorted by date, desc.

 

I have tried to update the sorting setting into "preferences", but it doesn't change a thing on the online shop.

 

I think the previous developer hard coded the SQL query in the template file.

 

The thing is, I can't find which file it is as I'm new in Prestashop.

 

Does anyone would have a idea which file it could be? Or maybe the issue could come from somewhere else?

 

I thought about updating prestashop, but I fear the previous developer modified other core files and the website uses a custom theme.

 

Thank you very much for your help guys!

 

Have a nice day.

Hi Daube,

 

If core has been modified, search in

- classes/Category.php

- controllers/CategoryController

 

Else in

- override/classes/Category.php

- override/controllers/CategoryController.php
