    The error might be related to your php version, if you use a version >= 7.3 the error shouldn't occur.since the signature of setcookie with the third parameter of type array was added in php version 7.3 – HelgeB Oct 22 '20 at 8:35
  • @HelgeB Yes, I am using PHP 7.3.23-4+ubuntu18.04.1. But not working. Any help? – Bojjaiah Oct 22 '20 at 9:03
  • @HelgeB The same error showing after upgraded PHP 7.4 also. – Bojjaiah Oct 22 '20 at 9:25

    does phpversion() returns the same version if you call it from CLI and via URL? What webserver do you use? If it's apache and you are using mod-php you should check that too – HelgeB Oct 22 '20 at 9:40

    So the issue was with incorrect php version used during running magento on web server and now it solved? – Ihor Sviziev Oct 23 '20 at 7:01

Just had this problem on a server. It was solved after I changed the nginx config to (before it was 7.2):

upstream fastcgi_backend { server unix:/var/run/php/php7.4-fpm.sock; }

And restarted nginx..

The issue is occurred due to the PHP older version. Check the PHP version print phpversion();.

Disable older version

sudo a2dismod php7.x

Enable PHP 7.4

sudo a2enmod php7.4

and restart apache2

sudo systemctl restart apache2

It's working good in my case


I think this answer will help you. After upgrade to PHP 7.4, you need to run setup upgrade and compile again. https://community.magento.com/t5/Magento-2-x-Technical-Issues/Magento-2-4-0-gt-2-4-1-Interceptor-Exception-After-Upgrade/td-p/461985


Use below commands and check

php bin/magento setup:di:compile rm -rf generated/code/ var/view_preprocessed/ var/page_cache

php bin/magento cache:clean php bin/magento cache:flush

Hope, your error will be solved.
