Some pages can no longer be edited (CCM_USER_REGISTERED = false)

Recently a few pages on my site can no longer be edited and CCM_USER_REGISTERED shows as false in source code. This includes the homepage. All of these pages were created by me, were previously editable and use the same templates as pages that are still able to be edited. There’s no unusual javascript or anything that would conflict. I am the admin on the account and have deleted cache files to see if that helps, as well as using different browsers. I can’t think of anything else to look for. It seems like Concrete randomly revoked editing permissions for these pages. Any ideas?
