Just a reminder that #Anahita isn't yet compatible with PHP 7.4. The latest you can go to is PHP 7.3.9. The list of upgrades for PHP 7.4 is long, because of significant changes introduced in this release: https://github.com/php/php-src/blob/PHP-7.4/UPGRADING
We are working on it. If you can lend us a hand, we appreciate it, too.
