Temporary problem with image galleries

After upgrading to WordPress 3.9.2 (as a critical security issue was detected with previous versions) with NextGEN 2.0.66.17 posts cannot be opened with the plugin activated. If I disable the plugin, the site works normal (obviously without galleries) but if I enable it, just the homepage works but I cannot access any post.

Which means I can only disable it for the moment and wait for the update…. :-(

I wrote a bug report on the WordPress plugin site and tweeted @nextgengallery and now wait for a solution. In the meantime, image gallery access will be disabled. Sorry for the inconvenience.
