Check the Apache logs for errors. The Apache log files are typically located in /var/log/apache or /var/log/httpd, but the location will depend on your operating system and how you installed Apache.

Check the Open XDMoD logs for errors. The Open XDMoD logs files are located in /var/log/xdmod if the RPM was installed or PREFIX/logs (e.g. /opt/xdmod/logs) if the source package was installed.
