I have been using Nextgen Gallery for a number of years, rather happily.
I have just noticed that the gallery settings on my blog have changed (e.g. this post: http://www.petersommer.com/blog/archaeology-history/macedonia-alexander-the-great/)
My galleries used to work in such a way that when clicking on an image, that image would open in front of the respective post, showing its caption below and “next” or “previous” arrows on the right and left. Now, the images simply open as new pages, with no captions.
My global Nextgen setting is to use show galleries as “Nextgen Basic Image Browser” with the template “NextGEN: album-extend.php”.
What am I doing wrong?
