deleting the `private` in v3.1 foldergallerypage.php, to allow the database to rebuild, takes it back to the same as my copy of v3.0.
I needed to copy back....,
(linking to the script.js) to the bottom of page.ss then the gallery and slideshow worked.
So the updates did not make any difference.
I have not had time to upload to a live site yet, but the only difference I made to gallerypage.ss is to include a header and a
content div which with the foldergallery in the css alters the width to 750px, making room for a right-hand sidebar
