Liste des coups aux jeu d'échecs disparus.

Bonjour,

Depuis quelques temps je n'ai plus d'affichage des coups joués sur mon site de jeu d'échecs dont voici en image ce qu'il en est plus exactement ici:

Je pense avoir localisé la raison de ce dysfonctionnement dont la cause serait le passage de mon serveur à PHP 7.1
Peut être que cela se passerait dans la fonction getMoves du fichier gui.inc.php que voici:

<?php
//session_start();
require_once 'chessutils.inc.php';

	if (isset($_SESSION['shared']) && $_SESSION['shared'] && ! $isPlayersTurn)
	{
		$perspective = ('white' == $_SESSION['player']['p_color']) ? 'black' : 'white';
	}
	else
	{
		$perspective = $_SESSION['player']['p_color'];
	}

	/* NOTE: if both players are using the same PC, in a sense it's always the players turn */
	if (isset($_SESSION['shared']) && $_SESSION['shared'])

Ainsi quelqu' un pourrait il m'aider où m'orienter afin que mon site retrouve la liste des coups qui existaient avant que le serveur ne face des modifications avec PHP7.1 ?

Merci d'avance.
