Menu problem after update from Lay 5 to 11

[calvinparis]

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!

hey! if i was you i would check
in appearance -> menus

if the right pages are linked there.

also, i think one of the pages is a category page?
you could

just go to that page, click "copy to pages"

and then link that new page in appearance - menus

also, i would try going to settings -> permalinks
and click "save" there. this refreshes links
