Hi again,
“Publish a New Entry” page -
Go to Content -> Publish
This screen will initially load in “edit mode”
Going to Content -> Publish only produce secondary menu with my 2 channels in it.
So I click on one, wait a while (everything is slow) and I get a blank page.
Your advise, please
P.S.
Maybe it all make sense at one point, but so far the tutorial is a series of seemly-unconnected moves that does not add up to a true understanding.
