I installed ImageGallery on another CMS( by other I mean another SilverStripe installation) and its giving me some strange errors. When I go into the CMS, I can create albums, add pictures, no problems there. However, when I go to the gallery page (Front end) I get nothing but a blank screen. basically a PHP error. Went through the error logs and am getting a sortable object error. Any ideas as to why... error below:
PHP fatal error: class sortable dataobject not found in imageGallery/_config.php
