### Changing Apache configurations post install.
Sometimes, you may want to change deployment settings post installation, for example: replacing the domain, port or protocol, or changing the system to use SSL or stop using SSL.
You can run `/opt/kaltura/bin/kaltura-front-config.sh` as many times as you'd like with different values. The script will re-configure the system accordingly.
For instance, you may want to change the service URL, port or protocol.
If you cannot find the problem, post the results of each step as well as the output for:
# grep ERROR /opt/kaltura/dwh/logs/*
