Bonjour,
Effectivement j'ai désactivé le module "PS Social with Facebook & Instagram v1.31.0" et le problème n'est plus présent.
Voici la portion de code du fichier PixelHandler.php
public function handleEvent($params, $hookName) { $pixel_id = $this->configurationAdapter->get(Config::PS_PIXEL_ID); if (empty($pixel_id)) { return ''; } $track = 'track'; $eventType = false; if (isset($params['event_type'])) { $eventType = $params['event_type']; } if (isset($params['user'])) { $userData = $params['user']; } $content = $eventData = []; if (isset($params['eventID'])) { $eventData = ['eventID' => $params['eventID']]; } if (isset($params['custom_data'])) { $content = $params['custom_data']; } $smartyVariables = [ 'pixel_fc' => $this->module->front_controller, 'id_pixel' => $pixel_id, 'type' => $eventType, 'content' => $this->formatPixel($content), 'track' => $track, 'eventData' => $this->formatPixel($eventData), ]; if (isset($userData)) { $smartyVariables['userInfos'] = $this->getCustomerInformation($userData); } $content = ''; if ($hookName === 'hookDisplayHeader') { $this->context->smarty->assign($smartyVariables); $content .= $this->module->display($this->module->getfilePath(), 'views/templates/hook/header.tpl'); } $this->context->smarty->assign($smartyVariables); $this->templateBuffer->add($this->module->display($this->module->getfilePath(), 'views/templates/hook/fbTrack.tpl')); // Return the existing content in case we have a display hook if (strpos($hookName, 'Display') === 4 && !$this->isCurrentRequestAnAjax()) { $content .= $this->templateBuffer->flush(); } return $content; }
