Enabling error reporting in PrestaShop

By default, error reporting in PrestaShop is disabled for security reasons. However, when troubleshooting issues such as blank pages or module errors, enabling error reporting can help identify the cause. On ruachost.com, you can enable error reporting by editing configuration files.

Why Enable Error Reporting?

• Helps diagnose problems with modules, themes, or custom code.
• Displays detailed error messages instead of blank pages.
• Useful for developers during debugging.

Steps to Enable Error Reporting

For PrestaShop 1.5.3 and Newer

1. Log in to your account using SSH or cPanel File Manager.

2. Navigate to your PrestaShop installation directory.

3. Open the file:

   config/defines.inc.php

4. Locate the following line:

   define('_PS_MODE_DEV_', false);

5. Change false to true:

   define('_PS_MODE_DEV_', true);

6. Save the file and exit. ✅ Error reporting is now enabled.

For PrestaShop Versions Older than 1.5.3

1. Log in to your account using SSH or cPanel File Manager.

2. Navigate to your PrestaShop installation directory.

3. Open the file:

   config/config.inc.php

4. Locate the following line:

   @ini_set('display_errors', 'off');

5. Change off to on:

   @ini_set('display_errors', 'on');

Important Notes

• Security caution: Error reporting should only be enabled temporarily for troubleshooting.
• Once the issue is resolved, disable error reporting again by reverting the changes (true → false or on → off).
• Leaving error reporting enabled on a live site may expose sensitive information.
