Troubleshooting

The first place to look if you're having problems is the Apache error logfile (/var/log/apache2/error_log). Also check that your file permissions are set correctly; in particular, make sure the user that Apache is running as has permissions to access the Mono application directory or directories. If you get a "Service Temporarily Unavailable" error, try changing the MonoServerPath directive to point to /usr/bin/mod-mono-server (the /usr/lib/mono/ location seems to work in some setups but not all).
