noob question as I can't really find answers to these anywhere on the site, sorry as this is my first post but I'm panicking
first of all; How can I install add-on's without composer? there is literally no documentation I've found about this.
second of all; when I flush, it leaves me with a blank page; I've tried doing this instead http://mysite.com/test/index.php/dev/build?flush=all
It will give me some sort of a token in the address bar but a 404 page; am I doing it properly?
