Problem categories listing in JM Modern HikaShop

-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4.0
-- Browser(s) name and version -- : Google Chrome Version 41.0.2272.76

Hello,

I'm french, so I'm sorry if the message isn't correct.

I bought the template JM Modern HikaShop to build a website for a client.
Unfortunately I updated Hikashop today (2.4), and since I have serious problems with the display of the categories.
The "categories listing" doesn't work anymore : when I click on the menus to go to the sub-categories, it shows nothing but the HikaShop copyright, or Lorem Ipsum text.
Why?
Could you help me please?

I solved the problem, thanks.
Nothing to do with the update!
I found the solution here : www.hikashop.com/forum/product-category-...-not-displaying.html

Bye
