Upgrade your PHP to minimum 7.1, I have currently no other solution for this.

[ReeCrema]

I upgrade to 7.4

PHP 7.4.15 (cli) (built: Feb 20 2021 05:33:45) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.15, Copyright (c), by Zend Technologies

but still the same error...

I tryied do in my Local Machine (windows) and everything works...
I think its something because Google Cloud VPS... But I dont find the problem...

You also need to update your apache2/nginx config to use that php version. This problem exist only on php version 7.0 and lower.

Hello!
Sorry, do you have any tutorials or what I need to conf in apache2?
I was looking, but I found nothing.

[slawkens]

Execute this in your terminal:

sudo a2dismod php7.0
sudo a2enmod php7.4
sudo service apache2 restart

[ReeCrema]
