I am having the same problem as well. First, the gallery disappeared from the page, then when I added it back in as a slideshow, the feed indicator turns forever (like Jwwaren mentioned). I’m currently using an image browser just so the images can be seen, but I’d like to use the slideshow.
I’m using WP 3.5.1, NGG Version 1.9.12. Would love to have some guidance on this issue.
