[Serusers] presence problem - sr-users

11 Mar 2006

I read the SER presence handbook as you told me, I follow the 
instructions to install ser with presence modules but i receive some 
erros and modules wasn't installed.
I go back to my old ser installation with pa module, configure some 
lines in ser.gfc to handle subscribe but now I'm receiving an error to 
SUSCRIBE and PUBLISH, it's like pa module can't process messages: 
Status: 400 Bad Request (ethereal)

this is my ser.cfg:

# ----------- global configuration parameters ------------------------

Do you have any idea of what's happening???
Thanks again...
