QuickContact Erreur PHP session_name()

[gasblack]

Bonjour à tous,

Novice en Joomla, je viens vers vous car j'ai un problème PHP avec quickcontact.

Voici le message d'erreur : Warning: session_name(): Cannot change session name when session is active in /var/www/html/joomla/modules/mod_je_quickcontact/mod_je_quickcontact.php on line 53

Je suis en php : 7.2.31-1+ubuntu18.04.1+deb.sury.org+1 et sur un serveur ubuntu personnel.

J'ai déja essayé de mettre la ligne 53 en commentaire, l'erreur disparaît mais je ne reçois aucun mail lorsque j'envoie un message.
J'ai aussi essayé de remplacer cette ligne 53 :

session_name("je_quickcontact");

par

session_id("je_quickcontact");

comme suggéré sur des forums de PHP, je n'ai plus d'erreur mais je ne reçois pas de mail.
J'ai également essayé de changer vers PHP 7.3 mais Joomla ne fonctionne plus du tout à ce moment là.

Voici le code du fichier mod_je_quickcontact.php:

Si vous auriez une solution que ce soit dans le code PHP ou autres.
Merci d'avance, et bonne journée à vous.
