I'm upgrading a site from v2.4 to v3.0.5 I finally got the site up and running, but none of the modules I've installed seem to registering. For instance, I converted a gallery page to the Photo Gallery detailed in this page: http://www.silverstriperesources.com/articles/how-to-make-a-photo-gallery-in-silverstripe-3/ . I uploaded both of the "GridFieldBulkEditingTools" and "SortableGridField" folders to my site's root, with the other main SS files. But when I load up the gallery page I get a "Fatal error: Class 'GridFieldBulkEditingTools' not found " error. Neither of those modules show in the /dev/build output.
I also have uploadify and htmlpurifier, neither of those show up in the /dev/build.
Is there's something that I could've done in the upgrade process that would make these modules not install?
