Alrighty… so I looked up some stuff and the error seemed to do with MariaDB. I noticed this weird thing. So one of the tutorials I followed was for MariaDB and another was for MySQL. I did the MySQL one second and when I did that I thought I saw it say something about uninstalling MariaDB. So I reinstalled MariaDB, and did the setup all over again.
I also found a post saying MariaDB only accepts localhost from 3307 so I put that in the localhost name andI got this new message!
Error while trying to create admin user: Failed to connect to the database: An exception occurred in driver: SQLSTATE[HY000] [2002] Connection refused
SO! It’s finding it now! it’s just not able to get in… maybe I need to… make a user for MariaDB? I would expect this webinstaller to do that or something but maybe it’s asking for login information for an already existing db?
