Error Logging

Error Logging

When debugging is disabled, there can be situations where PHP errors can cause a white screen, or there can be errors that are completely invisible to the user but result in incorrect execution of a given page.

To find these errors, it is recommended to enable logging in ExpressionEngine.

To enable error logging, you need to do the following:

1. Create a logs folder inside your system/user folder and make sure it’s writable
2. Open the config.php file and add the following config overrides:
   • log_threshold (required)
   • log_date_format (optional)

Example:

    $config['log_date_format'] = 'Y-m-d H:i:s';
    $config['log_threshold'] = '1';

After adding the two config file items above, PHP errors, warnings, etc. will be logged to a file with the corresponding date inside the system/user/logs folder.
