How to enable error reporting in PrestaShop

This article describes how to enable error reporting in PrestaShop. For security reasons, error reporting is disabled by default. However, if your site is experiencing problems, you may want to temporarily enable error reporting to help determine the cause.

Enabling error reporting

The steps to enable error reporting in PrestaShop depend on the version that you are running. Follow the appropriate procedure below for your PrestaShop version.

PrestaShop 1.5.3 and newer versions

To enable error reporting in PrestaShop 1.5.3 and newer versions, follow these steps:

1. Log in to your account using SSH.
   Alternatively, if your account includes cPanel, you can use the cPanel File Manager instead.
2. Use a text editor to open the config/defines.inc.php file in the directory where you installed PrestaShop.
3. Search for the following line in the config/defines.inc.php file:

   define('_PS_MODE_DEV_', false);

4. Modify the line as follows, changing false to true:
   

   define('_PS_MODE_DEV_', true);

5. Save the changes to the config/defines.inc.php file and exit the text editor. Error reporting is now enabled.
   

   For security reasons, you should disable error reporting when you are done troubleshooting. To do this, simply change the true value back to false.
