Debug Moodle(TM) LMS errors

NOTE: We are in the process of modifying the file structure and configuration for many Bitnami stacks. On account of these changes, the file paths stated in this guide may change depending on whether your Bitnami stack uses native Linux system packages (Approach A), or if it is a self-contained installation (Approach B). To identify your Bitnami installation type and what approach to follow, run the command below:

 $ test ! -f "/opt/bitnami/common/bin/openssl" && echo "Approach A: Using system packages." || echo "Approach B: Self-contained installation."

The output of the command indicates which approach (A or B) is used by the installation, and will allow you to identify the paths, configuration and commands to use in this guide. Refer to the FAQ for more information on these changes.

Troubleshoot domain name errors

You may see an error like the following:

PHP Notice: Undefined index: HTTP_HOST in /opt/bitnami/apps/moodle/htdocs/config.php

To resolve this specify your domain name or IP address in the Moodle(TM) LMS configuration file as shown below:

$CFG->wwwroot   = 'http://SERVER-IP/moodle';

NOTE: Depending on your installation type, the Moodle LMS configuration file will be located in the following paths:

  • Approach A (Bitnami installations using system packages): /opt/bitnami/moodle/config.php

  • Approach B (Self-contained Bitnami installations): /opt/bitnami/apps/moodle/htdocs/config.php
