All shoutbox modules seems not working on PN75?

I mean, in localhost all of them work perfectly but when i try to use them on web every one of them send a diferent error :S
in PNShoutbox from pncommunity.de when you press the shout buttom ive been sent to a new page with this message:

"you can't access this file directly" :O
Hi,

there is an error in that module which was corrected by the author in cvs

just download this file then the shoutbox works correct again.

rgds,

I used Vistra shoutbox in the end - works great no probs (apart you have to manually configure its own CSS but takes 1 min)
