It appears that the 7.50.0 configuration wizard has removed the optional “Next - for continued configuration” at the end of the main install wizard. This asked about three more things:
Store passwords in plain text
Leave the MariaDB defaults
Store SSLs in home directories vs /etc/ssl
Can I still effect changes to these somewhere else in the web interface?
To add to this: You should not use those old template configs anymore. They were from decades ago, the software has changed dramatically and the hardware we’re running it on has changed dramatically. Back when those old template configs were made, >1GB of RAM was “large”, now it is tiny.
