Why Am I Seeing a Blank Page Instead of Error Messages in CodeIgniter?

CodeIgniter Error Handling: Display Error Messages

In CodeIgniter, encountering a blank page instead of error messages can be frustrating. To troubleshoot this issue and display PHP error messages, follow these steps:

1. Ensure Error Reporting is Enabled:

Ensure that error reporting is enabled by adding ini_set('display_errors', 1); to the top of your index.php file. This explicitly instructs PHP to display errors.

2. Configure Environment Settings:

In your index.php file, configure the error reporting level according to your environment. For development, set error_reporting(E_ALL); and ini_set('display_errors', 1); to display all errors.

3. Check Apache Configuration (Ubuntu):

For Ubuntu with Apache, ensure that the display_errors directive is set to On in your Apache configuration files:

<IfModule mod_php5.c>
  php_flag display_errors On
</IfModule>

4. Restart Apache:

After updating the Apache configuration, restart Apache using the following command:

sudo service apache2 restart

These steps should enable PHP error messages to be displayed in CodeIgniter. You can now debug and resolve errors effectively.
