I too experience similar problems and here is a description and hope it helps in solving this bug.
Add gallery/Images – when I press the button add gallery – nothing happens
the same with Import image folder – button
I can upload and those functions are normal
In Manage Gallery and in Gallery settings (at the top)- there is blank.
(is there supposed to be something – besides the text?)
actions like move images beetwen galleries functions alright!
In Album – I can′t create albums
sort gallery is blank – (is there supposed to be something…?)
basically the problem here seems to be that I can′t create galleries and albums by pushing the buttons
I think this did come about in nextgen 1.1.0 and now also in 1.2.0
I have WordPress 2.7.1 and use Plugin Central (without errors)
