I did it and ran into this:
"This page isn’t working 18.104.22.168 is currently unable to handle this request."
I checked current forum and saw that the settings are:
Flarum 0.1.0-beta.8.1, PHP 7.3.7, MySQL 5.7.23-log
My Installed version are:
Flarum v0.1.0-beta.9, PHP 7.2 , MySQL 5.7.27
Not sure if these are the causes of the problem
