Issue with a collection after a backup

Hello !
I recently performed a backup of my website. Subsequently, I encountered a temporary issue where all article links were broken. Although this problem resolved spontaneously after a few minutes, I am now facing a persistent issue on the “Actualités” page of my website (Nos Actualités sur la prospection commerciale B2B - ReCom).

Despite the articles being visibly listed, clicking on any article link results in no action—essentially, the links are unresponsive. It appears there may be a disconnection or misconfiguration between the overview page and the individual articles. The database containing all articles is intact, suggesting that the issue lies in the linkage rather than the content itself.

The collection with all of the articles is still there, but I feel like the connection between this page ang each articles broke.

Can someone help ?
