I came here because I had trouble installing Phpmyadmin on Ubuntu after I upgrade from php 7.0 to 7.1

Here is the tricks

2) Install php modules

sudo apt-get install php7.1-mbstring
sudo apt-get install php7.1-mcrypt

sudo a2enmod php7.1

And of course restart your server (apache in this case)

sudo systemctl restart apache2
