After activating debug mode, I was able to see the error in the Console > Network. Apparently this is the error :
Compile Error: Cannot declare class WishList, because the name is already in use (500 Internal Server Error)
And more in details :
Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalErrorException: "Compile Error: Cannot declare class WishList, because the name is already in use" at /var/www/vhosts/web22.sebweb.fr/httpdocs/lits-magination.eu/modules/leofeature/classes/WishList.php line 566
What I am supposed to do when this error occurs?
