Hello @Jerome:
We have tested Foodie World Pro with the latest PHP version 8.4 and confirmed its compatibility. Our current systems are running PHP 8.3, and throughout development and deployment, we have not encountered any compatibility issues or unexpected behavior.
Can you please check disabling the plugins one by one? It might be a plugin issue.
And also, please go through the link below, it might help you.
