Updating killed the gallery

We are running the latest WP and NGG after having upgraded through admin. We’re on Powweb and have successfully used the plugin for several years. After updating to the latest WP and then doing the NGG update through plugins, a lot of things broke. No newly installed plugins, no template changes. Here’s what’s happening:

1. After loading our Photos page which is at ourdomain.com/media/photos like it’s always been, you see the basic compact thumbnails with all our galleries listed just like before. However, if you click on a gallery, it just reloads the photo page. I went into manage galleries and checked out the page linked to field and they say Photos. I changed a couple to unlinked. When I did this, those galleries opened ourdomain.com/media/photos/nggallery/galleryname with only a note that says “no images were found.”

2. I finally figured out if I created a new page for a gallery, that would load the page of thumbnails correctly, and the fancybox loads when you click a thumbnail as it’s supposed to, so long as you’re not using Opera.

We’ve never had to create a new page before and if we do, we’ll have a hundred extra pages and a really cluttered admin pages section. I tried deactivating plugins. Nothing seems to conflict. We have no idea why it suddenly started doing this. Is there a way to make it work like it used to or have things changed so we now have to create new pages for each gallery?

Thanks!
