From time to time, instead of site content, you may see the default Apache page or another page of the default site. In /var/log/sw-cp-server/error_log the following message appears:
/bin/sh: /usr/share/sso/sso-ssl-conf.sh: not found
Note, that described issue is actual only for Deb-based systems.
CauseThe "sw-sso" package was removed, but the configuration files remained.
ResolutionYou can find packages that were not removed completely with this command:
# dpkg -l | grep 'sw-\|psa' | grep '^rc'
Then remove the package with:
# dpkg --purge sw-sso
And restart the sw-cp-server:
# /etc/init.d/sw-cp-server restart
