Answer of my host : " it is probably because of your PHP version. In your control panel, go to your domain > manage > PHP options > lower it to 7.3
Then wait about 10 minutes and test your site again. It most likely has to do with a CMS update that doesn't work well with the chosen PHP version.
CMS is the core of your website. In your case this appears to be 'symfony' based on your error outputs."
I have replaced the PHP 8 to PHP 7.3 an i replaced symfony of the original download PHPBB3.3.4 but after resett PHP 8 again, the same errors occures
How i can get back PHP 8?
