Password error. Cinnamon. Linux518

I decided to install LAMP as described in this article: https://forum.manjaro.org/t/howto-install-apache-mariadb-mysql-php-lamp/13000
First I installed Apache. The status is OK!
Next I installed MariaDB.
It gave me an error and now the password to the user account does not work!
What to do?
I’ve been in Linux for a couple of days now!
I left Windows.

Why did you move the theme to LAMP if the password does not match the Linux User account?
