Hello, I have this same problem, blank page on the following pages:
– Add Gallery / Images (admin.php?page=ngg_addgallery)
– Gallery Settings (admin.php?page=ngg_display_settings)
– Other Options (admin.php?page=ngg_other_options)
Additionally, it is preventing the toolbar (“kitchen sink”) from loading on the “Visual” tab of the visual editor for pages/posts.

I’ve tested disabling the nextgen plugin and when I refresh page, the visual editor loads fine.
I do web development and am fairly familiar with the WordPress framework, so if you need additional debug info please let me know.
