Enabling Error Output in Prestashop

Prestаshоp has a developer mode (dev mode). This mode is needed for outputting debugging information such as errors, warnings etc.  This mode can be useful if the user applies some changes into Prestаshоp, for example installs a new module or theme, and after that some problems in the store performance begin to appear. In such cases, in order to nail down the cause of the problem, the store is switched into the developer mode.

Before enabling the developer mode you should disable Smarty cache and CCC (Combine, Compress and Cache). Smarty Cache  is disabled in BackOffice / Advanced Parameters / Performance / Smarty.

The dev mode is enabled as follows:
1. Go to the directories [rооt_prestаshоp] /config/. [root_prestashop] – Prestshop root directories;
2. Open the file defines.inc.php;
3. In the file defines.inc.php find the line define( ‘_PS_MODE_DEV_’, false);  
4. Replace the line define( ‘_PS_MODE_DEV_’, false) with define( ‘_PS_MODE_DEV_’, true) and save the changes.
