Why can't I setup any trades?

I've recently tried to initiate trades with two different traders. But all I get is

Failed. This can happen for several reasons
- You tried to initiate a trade with yourself
- You included a link in the subject (add it later in the "notes" field)
- Your subject was too short. Make it meaningful.


Never lets me enter anything, just straight to that error.
