I am having problems viewing the history of each of my pages in Silverstripe. Essentially, whenever I click on the Version History tab to view a list of all the previous versions of my pages, the panel displays 'loading...' and then nothing comes up. No version history is available for any of the pages in the CMS, even though I have edited and modified these pages multiple times. Is there something I need to do to enable version history tracking?

I read in the forums that the DB table, SiteTree_versions, is where the history is stored. So I checked the database and SiteTree_versions is full of records. Any idea why these versions are not listed in the CMS?

Thanks!
