If it produces an error message rather than a lot of HTML, that would be valuable information. If that doesn't help, have a look at /var/spool/ppr/logs/ppr-httpd. If it doesn't exist, do: # chown ppr:ppr /var/spool/ppr/logs # chmod 775 /var/spool/ppr/logs then kill ppr-httpd (to make sure you get a new one) and try again. The permissions are supposed to be set as above, but I think there may be or have been a problem with them.
