Well, I think I know why you get this : I noticed 
that some browsers sometime do a reload after 
posting a message or try to post a totaly empty 
form. That was causing those empty messages... I 
fixed it to prevent it but currently no page is 
returned when it happen so you get this error...

Thanks but I fully wrote the forum software so I 
don't think you can help much... :) (except if you 
want to look at 20000 lines of code in C...:)
