Can I reinstall/install Mariadb?
I think that I forgot to enable mariadb option
I can not run wordpress quick installation I see this error
Error: DB_SYSTEM is not enabled
How to solve this problem
Not knowing all the intricacies of HestiaCP guts and knobs apt install mariadb-client mariadb-common mariadb-server followed by editing /usr/local/hestia/conf/hestia.conf and changing from DB_SYSTEM=‘’ to DB_SYSTEM=‘mysql’ should get you started.
