After uploading image_gallery and running /dev/build i get this error:
Fatal error: Class 'SortableDataObject' not found in lombardisbbq.com/image_gallery/_config.php on line 2
This is what my _config.php looks like:
(it's default from extracting it after the download)
<?php
SortableDataObject::add_sortable_classes(array(
"ImageGalleryItem",
"ImageGalleryAlbum"
));
DataObject::add_extension("SiteTree","ImageGallerySiteTree");
?>
Any thoughts here?
