Can not reply to threads.

When i try to post a reply to a post in a thread the system is not taking it. I write my msg, click post the button and post button disappears, but nothing else happens. The page stays the same, If i refresh the page my post still does not a appear.

I think the post button link is broken. I have now tried this on 2 pc from collage and my home one.

Edit: seems fixed now, thanks Rioter Affordance
