Forums mIRC Help unable to see any messages typed by other users.

well this is kind of strange.

i can't see any messages, on any channel. i've been using mirc for a few years now, and have no idea what's up. i can see joins and parts, but no messages. i can get queried, that i can see. but on channels, it's all just joins, parts, kicks and bans.

any help would be much appreciated.
