Thanks for the replies. I have erased and reinstalled the qp (/usr/local/lib/python/site-package/qp ) module make sure there are no lingering older extra files. Here are the results of the suggested commands. [toto@mydesktop extreme]$ echo $HOME /home/toto [toto@mydesktop extreme]$ qp -c extreme Overwriting info=from scipy.misc (was from numpy.lib.utils) sci = lin = SITE: extreme This site demonstrates authentication, sessions, static files, and exception reporting. publisher root_directory banned /home/toto/qp_sites/var/extreme.banned logfile : '/home/toto/qp_sites/var/extreme.log' durus_pidfile : '/home/toto/qp_sites/var/extreme.durus.pid' web_pidfile : '/home/toto/qp_sites/var/extreme.web.pid' durus_address : ('localhost', 7003) http_address : ('', 8003) as_https_address : ('localhost', 9003) https_address : ('localhost', 10003) scgi_address : None [toto@mydesktop extreme]$ Hope this will help solve my problem.
