 * When I want to change php version, from 7.1 to 7.2 or 7.4, a critical error that
   targets E-transactions (0.9.9.9.3) occurs at the time of payment, what can I 
   do?

 * Salut Claude,
 * J’ai ouvert un sujet deux semaines avant le tiens ici même, aucune réponse également.
   
   Le soucis c’est que l’on va être obligé de mettre à jour nos versions de PHP 
   prochainement et rien ne semble les affoler…

 * Salut Josselyn,
    J’ai eu une réponse directe `De : Support E-transactions <support.
   e-transactions@avem-groupe.com> que j’avais contacté directement par ailleurs.
   Et ça marche ! c’était aussi simple que ça ! A toi de jouer, bonne chance, Claude
   ______________________________________ “**Bonjour, Après avoir changé la version
   php de votre serveur je vous invite à désinstaller/réinstaller le module e-Transactions.
   Pensez cependant à copier les identifiants présent dans le module avant de le
   désinstaller (Clé HMAC, numéro de site, rang, identifiant). Le module est compatible
   avec les anciennes versions comme les nouvelles version de php cependant il ne
   s’adapte pas dynamiquement à la version php de votre serveur. C’est pourquoi 
   il est nécessaire de le désinstaller/réinstaller.”
