I just installed JA Edenite II v2.0.0 with T3 v3.0.7, manually over an existing test site and template, intending to convert to Edenite II.
The button on the left is not present in my pre-Edenite site
and when I click on it it opens an empty sidebar
I've gone through the docs and searched the forum, and I'm sure I'm missing something very basic.
