I just uploaded NGG to a brand new WP site - with everything the latest and greatest releases - the self test failed and I couldn't even upload one picture.
NGG was my absolute TOP favorite plug-in and I really like the new interface and workflow. I can't tell you how disappointed I am that this formerly awesome plug-in doesn't work anymore.
And since theme creators have NO concept of how image galleries SHOULD work, I'm now in the market for a new gallery plug-in...
