I use the nggallery shortcode to place a gallery of thumbnails in a post. Because I only allow 21 thumbnails to be displayed at a time, and my galleries contain more photos, the gallery gets split into several pages. So far, so good.
If I click on one of the thumbnails, and keep clicking Next, I can move through the entire gallery. So far, so good.
BUT: If I instead click on one of the boxed page numbers displayed beneath the gallery, I get the following error:
"No Results Found
The page you requested could not be found. Try refining your search, or use the navigation above to locate the post."
It used to work, and I'm not sure when it stopped working. I'm using the Aggregate theme from Elegant Themes.
Do I need one of the helper plugins to make this work? At the moment, I only have the primary NextGEN Gallery plugin installed.
