Looks like an Admin has turned off the Article Comments feature [Probably because it looks like you've switched to the new forums which added the discussion module instead].

Unfortunately, those comments are just gone. AFAIK, there is no way to access them with the feature disabled. The server is still storing them so they aren't deleted, but you can't access them unless you are an Admin and turn Article Comments back on.
