Problem

When im in a channel, i’'ve been idle for a while then i back and want to send message in the channel but i cant “*** ERROR (404): (null)”

What client are you using? By default, idle users will be kicked afrom the chat after a period of inactivity (this will be configurable in the next release). I would think that most clients would give you a nicer error message, though.
