Gallery will not work with 2.0 – Call to undefined function nggShowGallery

Hello,

First of all I have downgraded and restored service.

Call to undefined function nggShowGallery. Line 28 fails which is the last line in this PHP code. Any idea what changes with the 2.0 upgrade?

if (! (class_exists(‘nggallery’) || class_exists(‘nggGallery’)) ) return;

function get_listing_gallerydropdown($currid = ”) {
// generates option list for edit dialogs
get_nextgengallery_dropdown($currid);
}
function listings_showfirstpic($galleryid,$class = ”) {
// inserts IMG tag for thumbnail
return nextgengallery_showfirstpic($galleryid,$class);
}
function listings_nggshowgallery($galleryid) {
if (!$galleryid) return;

echo nggShowGallery($galleryid);
}

Thanks
