Internal server error (HTTP Error 500) after installing phpmyadmin on a certain domain

Question

I\'m getting internal server error (HTTP Error 500) after installing phpmyadmin on a certain domain.

This is what my config.inc.php file currently reads

Answer 1

Ensure that your PHP version matches the used PHP module in Apache2:

php -v  //PHP 7.4.4 
ls -d /etc/apache2/mods-enabled/php*.conf // php7.3.conf

sudo a2dismod php7.3  // disable 7.3
sudo a2enmod php7.4   // enable 7.4
sudo systemctl restart apache2

I installed the php-mbstring php-gettext (also excplicitly for latest PHP version), but it still wasn't working. At least it took me hours until I noticed apache decides itself what PHP version is used.
