Creating Date Poll results in "white screen"
Dear all, Apologize, but I'm not an expert with these things, but I would be very happy to get it back to work... I'm running nginx 1.21 on Ubuntu 20.04LTS with PHP 8.0.5. I can configure the poll, but when I confirm, nginx logs the following...
2021/06/27 00:22:13 [error] 2725624#2725624: *12724 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Undefined constant "PHPMailer\PHPMailer\FILTER_FLAG_HOST_REQUIRED" in /var/www/framadate/vendor/phpmailer/phpmailer/src/PHPMailer.php:3599 Stack trace: #0 /var/www/framadate/vendor/phpmailer/phpmailer/src/PHPMailer.php(3565): PHPMailer\PHPMailer\PHPMailer::isValidHost() #1 /var/www/framadate/vendor/phpmailer/phpmailer/src/PHPMailer.php(2304): PHPMailer\PHPMailer\PHPMailer->serverHostname() #2 /var/www/framadate/vendor/phpmailer/phpmailer/src/PHPMailer.php(1421): PHPMailer\PHPMailer\PHPMailer->createHeader() #3 /var/www/framadate/vendor/phpmailer/phpmailer/src/PHPMailer.php(1316): PHPMailer\PHPMailer\PHPMailer->preSend() #4 /var/www/framadate/app/classes/Framadate/Services/MailService.php(58): PHPMailer\PHPMailer\PHPMailer->send() #5 /var/www/framadate/create_date_poll.php(239): Framadate\Services\MailService->send() #6 {main} thrown in /var/www/framadate/vendor/phpmailer/phpmailer/src/PHPMailer.php on line 3599" while reading response header from upstream, client: 93.215.83.135, server: date.escher.cc, request: "POST /create_date_poll.php HTTP/2.0", upstream: "fastcgi://unix:/run/php/php8.0-fpm.sock:", host: "date.escher.cc"
Maybe someone can help me troubleshooting?? Thanks a lot
