Cannot reply to comments (weird error)

[sic22]

I successfully replied to one comment and then this error started occuring:

It happens under every article when I hit the "reply" button. Adblock doesn't change anything.

That's no good. I can have it looked into. In the meantime, have you tried any troubleshooting, like clearing your cache/cookies, or a different browser?
