Hi Chris!
Yes I can definitely confirm that data is showing in all of the DB tables. I have about 420 lines in the postmeta table alone (I am using Advanced Custom Fields to store a lot of data for the site).
Another note, if it helps, would be that i'm not using the traditional wp_ prefix for my tables as I was under the impression doing so could be a potential security flaw.
Let me know if that helps your diagnosis (if any).
Thanks for the quick response!
