Answer 1

I faced this problem when I upgraded my PHP to 7.3

I found mcrypt.so was still present in /etc/php/7.3 that should not be as it is deprecated in php 7.3 so just deleting mcrypt.so from /etc/php/7.3 solved issue.

I used following commands:

cd /etc/php/7.3

sudo rm -rf mcrypt.so

sudo service apache2 restart
