Featured products

Bonjour,
Oui, j'ai encore procédé à une mise à jour ce matin...
Merci - Bonne journée

Hello, no, the problem remains ...
When I click on the star of a product in the list of products (star checked), I want to put it forward, and I expect to see it appear in the Block 'focus' of my homepage (see screenshots) but nothing happens ...
Only the old appearances are displayed, even if I uncheck the star box of the list (?)
On the other hand, the display of the shop is really unstable and works once in two. I will try to make it run on a PHP7 server.
Tell me if you have any idea of my problem ...
Thank you, see you soon
