Problem with messaging to help, defiant events etc

Hey guys, when I try to send a message to the Help tab, or Defiant Events tab, or any other tab for that matter, I receive an error message.

The message is:

"Usage:h takes 0 args, you gave 4.
Show help window
h"

Thanks for your help!

I really do need pretty urgent help as I like to use these alot, any ideas?

Help channel is sorted by typing /hc before your message... Not sure about Defiant events.

Thanks for the help, it sorted the help channel.

And Defiant events seems to be fine after a deletion and a re-join.
