Interesting bug. I'm curious if anyone else has run into it. I'm even MORE curious if anyone has a solution since this site is 80% done.
When I logged onto my Drupal 7 site today to add a "page" I got the alert: "You have not created any content types yet."
Well I got news for you site... I have been creating content on you for weeks and there are most certainly content types listed at admin/structure/types. I see them right there. The defaults plus another one I made. But somehow YOU don't see them. If I add a fifth new content type, that one gets seen. But the other ones, that are used by Views and are already configured, those are not seen.
So anyone have a suggestion as to how I might "nudge" my site to "see" these content types again?
