[Plugin: NextGEN Gallery] 404 error on imagebrowser static pages

Since upgrading to WP 3.4, my galleries do not work correctly.

I’ve configured my setup to display a thumbnail grid on a static page and each image on its own page with and “next” and “previous” buttons on the bottom. The thumbnails continue to display, but clicking any of them results in a 404 Page Not Found error.

Example: https://www.nycaviation.com/photo-galleries/jones-beach-airshow-2012-preview/

Anyone know how to fix this?

Thanks.
