Hello,
I am troubleshooting a small website designed by someone else. It was recently hacked through an older version of Wordpress. I have updated Wordpress, PHP and plugins. Version 5 of Lay theme is used. I tried updating to the current version 11 (big jump), but there are menu problems so I have reverted.
Link to website: https://ifbproductions.fr
Under v11, the menu item "VOIR LES FILMS" (https://ifbproductions.fr/category/films/), incorrectly displays the same content as the menu item "PROJECTIONS" (https://ifbproductions.fr/projections/).
See images:

02 PROJECTIONS.jpg :

What changes do I need to make to fix this problem?
Thanks!
