Because the debugging console might display private information, make sure to only enable it when in maintenance mode. Do not keep it enable on a production store.

Debug mode

New in 1.6.

When in debug mode, you can choose to lessen the impact of certain features on PrestaShop, in order to best pinpoint where an error comes from:

  • Disable non PrestaShop modules. PrestaShop's own module are heavily tested and should present no issue whatsoever. If you enable this setting, you will be able to tell if the problem comes from PrestaShop's own code (core or module), or from a third-party module.
  • Disable all overrides. Many features in PrestaShop can be overridden. If you enable this settings, all overriding code will be disabled, and you will be able to tell if the problem comes from PrestaShop's own code, or from a third-party override.

Optional features

Some PrestaShop features can be disabled if you do not use them, as they can slow down your shop.

  1. Create a subdomain for your store's domain name, for instance http://cdn1.mystore.com (the way to do that depend on your host, ask him about it).

  2. Put a .htaccess file at the root of the subdomain. That file should contain a single line:

    Code Block
    Redirect Permanent / http://cdn-adresse.com


    Replace the http://cdn-adresse.com with the one from your CDN server. This way, you are creating an automatic redirection from your subdomain to your CDN server.

  3. Once the subdomain is in place, add it in the first field, "Media server #1". If that host allows for more web addresses, create as many subdomains to your store's main domain name.

  • File system. The static files are simply stored as any other file, on your server. This displays a field set to "1" by default. This is the file-system directory depth. Only change this value when you know what you are doing.
  • Memcached. A distributed caching system. Very effective, above all with multiple servers, but you need to make sure that your servers/hosts support it – most probably, if your PHP configuration features the Memcached PECL extension, you are good to go (you can download it here: http://pecl.php.net/package/memcache). You can add Memcached servers by clicking on the "Add server" link.
  • APC. Alternative PHP Cache is free, open and robust, but only works with one server – which is the usual case when you start your online business. Again, check for the availability of the APC PECL extension on your server: http://pecl.php.net/package/APC.
  • Xcache. Xcache is a new cache system, which is specific to the Lighttpd server – hence, it will not work with the popular Apache server. Read more about it at http://xcache.lighttpd.net/.
