If problems appear, for example, Apache does not display a page or does not display it correctly, the following procedures can help find the problems. First, take a look at the error log and check if the messages it contains reveal the error. The general error log is /var/log/apache2/error_log.

A proven approach is to track the log files in a console to see how the server reacts to an access. This can be done by entering the following command in a root console.

tail -f /var/log/apache2/*_log
