Forum software or server keeps acting up

[Tristanjohn]

For the past three or four days I've received the following message when I try to reply to a post:

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.

This is only site where this happens to me so I've got to believe the problem's on this end. Anyone know what's causing this? Can it be fixed? Someone working on it already?

Thanks.
