For some reason I can't get the Ninja Tables menu item to be visible in the backend dashboard for any role other than Administrator, even if I create a new role with the Administrator capabilities. Any ideas? Thanks.
DougDavis it is most likely that Ninja Tables are very explicit about who has access to this page. I'm not familiar with that plugin and most likely that it requires more than just the administrator capability.
Note! Make sure that any capability that you create is all lowercases. I've noticed that you wrote Administrator capability instead of administrator.
