Profile Problem

I have 2 problems, which are probably related.
First, I can't comment, though I have never even been disemvoweled. I hit the submit button and nothing happens. The "x" and reply buttons still work though.
Second, I can access my user profile, but clicking on any of the links does nothing (same with someone else's profile).

This issue exists on Kotaku and io9, but not consumerist. My user name is Tiber.
