Whether you’re a beginner or an experienced user, this guide will provide you with valuable insights into Moodle’s debugging capabilities.

Section 1: Understanding Moodle Debug Mode

Before we dive into the step-by-step process, let’s start by understanding what Moodle debug mode is and why it’s important.

Moodle debug mode is a built-in feature that provides detailed information about errors, warnings, and other issues within your Moodle site. It helps administrators and developers identify and resolve problems efficiently.

Section 2: Why Debugging in Moodle Matters

In this section, we’ll discuss the importance of debugging in Moodle and how it can save you time and effort.

Moodle Troubleshooting

  • Moodle is a complex platform, and errors can occur for various reasons. Debugging helps pinpoint the source of issues, such as broken plugins, misconfigurations, or incompatible themes.

Moodle Error Messages

  • Error messages are your clues to what’s wrong in Moodle. Debug mode reveals these messages, making it easier to address issues promptly.

Section 3: Enabling Debug Mode

Now, let’s get into the nitty-gritty of enabling debug mode in Moodle.

Debugging Settings in Moodle

  1. Log in to your Moodle site with administrator privileges.
  2. Go to the “Site administration” section.
  3. Click on “Development” under the “Advanced features” category.
  4. Look for the “Debugging” section, and you’ll see an option labeled “Debug messages.”
  5. Select “DEVELOPER,” which provides detailed debugging information, or “DEVELOPER_EXTRA” for even more information.
  6. Click “Save changes.”

Congratulations, you’ve successfully enabled debug mode in Moodle!

Enabling Debug Mode from config.php File

  1. In addition to enabling debug mode from the Moodle interface, you can also enable it by editing the config.php file. Locate the config.php file in your Moodle installation directory.
  2. Open the config.php file using a text editor or an integrated development environment (IDE).
  3. Add the following code before the line: require_once(__DIR__ . '/lib/setup.php');
    @error_reporting(E_ALL | E_STRICT);
    @ini_set('display_errors', '1');
    $CFG->debug = (E_ALL | E_STRICT);
    $CFG->debugdisplay = 1;

Now, you’ve successfully enabled debug mode in Moodle from the config.php file.
