Extension mysqli is missing, showing error, phpmyadmin doesn't work
With Latest phpMyAdmin versions require mysqli extension and will no longer work with mysql one (include extra "i" at the end of its name).
For PHP 7.3
sudo apt-get install php7.3-mysqli
For PHP 8
sudo apt-get install php8.0-mysqli
Will install package containing both old one and the new one, so afterwards all you need to do is to add
extension=mysqli.so
in your php.ini, under the subject Dynamic Extensions.
Restart apache:
sudo systemctl restart apache2
Authenticate if needed and press enter.
Should be done! If problem still occurs remove the browser cache.
