My node/add page (Add Content) shows two of every content type!
Here is a screenshot:
I am 99% sure this is is a database problem, but my database node_type table looks OK and only has one of each type.
I have disabled every module I could, updated everything, and have no errors in the log.
When I point my installation at a fresh database I do not have the problem. When I point a fresh Drupal installation at my current database I do have the problem. It seems like database to me.
Using Drupal 7.15.
Any idea on how to fix this?
