We we think we found the final issue with the gallery shortcode. Here’s another link to a zip file that should correct the problem. There’s just one file in the zip file this time, photo.php. You’ll have to replace the existing file with this new file.
photo.php goes in the /intense/templates/gallery/subtle/ folder
We’re sorry it took us so long to track this down. We will be submitting an update soon that will include these fixes.
