Yeah, okay, on that one, it doesn't work.
I checked another older post after that one, just to make sure it wasn't just the one you're talking about. But it didn't work, either. Based on that, I'm thinking that the site has a plugin installed to disable commenting after a certain period of time. (In that case, there should be a way for whoever's in charge of the backend to fix it so that, when commenting becomes disabled, the link says "Commenting Disabled" instead of "Leave Comment".)
Now you're all gone, got your makeup
on, and you're not coming back
