I installed the phpMyAdmin app and I changed the password as the first step. I am now getting this message at the bottom of the screen:
mysqli::real_connect(): (HY000/1045): Access denied for user 'phpmyadmin'@'localhost' (using password: YES)
According this https://tehnoblog.org/phpmyadmin-error- ... on-failed/ site, this occurs when one changes the password and suggests to change the /etc/phpmyadmin/config-db.php file, but the phpmyadmin files don't exit in that location.
Also I have installed php Address Book, and I don't see its database with phpMyAdmin.
