Hello to All,
I installed module Gallery Assist. Installation was fine and the module was enabled. All needed directories ..files/gallery_assist creation and saved options operation were successfully.
From there I did RTFM (Read The Finest Manual) and also watched the tutorial video (see 'Create your first Gallery') for a Gallery setup and creation. Administer->Site configuration->Gallery assist is also fine. And indeed my content Image received two new items menu linked to Gallery Assist.
But now how to create a new Gallery ? The problem is I cannot found any content Galllery (under menu Create content) to be able to create a Gallery content...
I used to test this module few months ago, but then I removed it : maybe the problem is related : so how to re-install and re-enabled it in case of a incompleted removal operation ?
Solved. The menu item Create Content -> Gallery Assist was simply disabled.
