I just migrated one of my websites that I use K2 with over to a new server but for some reason the K2 Categories disappeared? They still show up listed in the group assigned to them in the backend, but in the Categories tab in the backend, they don't display? They also don't show up in the front end when listing content. I migrated another site earlier this week with no issues from the old server to the new that also used K2. I checked in the MySQL database and they do display in the proper k2_categories table.Any clues?
