I did an upgrade to latest NextGEN Gallery 184.108.40.206. It's a gallery blog with https interface for Dashboard: http://galerie.blackseals.net
If I use the web editor for posts or sites and want to attach a nextgen gallery to it, then I see only an empty window with no buttons or fields...
Please for help.
edit: if I disable https for Dashboard, I'm able to attach NextGen Gallery to Post or Sites... it seems to me, it's a bug.
