I apologize in advance for the possibly amateur question but I decided that I must start asking questions to more experienced people in order to get experienced myself.
I was trying to follow Arch Wiki’s installation guide for wordpress wordpress with just a limited Linux knowledge. I messed up the installation and I was trying to revert my changes to try again but even if I uninstall mariadb with sudo pacman -R mariadb
and reinstall it with sudo pacman -S mariadb
it still keeps the previous configurations. My question is how do I remove Mariadb and its configuration files?
