I just replace the files, I refresh the page, and ALL works great, thanks a lot !
I still have a little problem with the scroll, but it's my fault, I think it's due to my layout for articles : In fact, I had to modify some php files of the module to have my desired layout, but normally, I should only modify the CSS files.
I ask you a lot, but could you try to reproduce this layout, only modifying GK4 CSS, and some options of the module ? I'm sure it's possible to do that properly...
Desired layout :

The label in red is the article category, below it's the title, and next the beginning of the intro text. Finally, it's the readmore link
Thanks again
Edit : It's ok, I delete some margin and it solves the scroll bugs
