Ultimate SEO URLs for Zen Cart – Installation

[hidpros]

I don't have this sting in includes-->application_top.php. As it mentions it in the install instructions.

Can i add the new code , what should i do?
require(DIR_WS_LANGUAGES . $template_dir_select . $_SESSION['language'] . '.php');

// include the extra language translations
include(DIR_WS_MODULES . 'extra_definitions.php');

Hi,

As a newbie I have read the information attached to your post and still do not understand it. I am not a coder. In simple terms what is the contribution supposed to do and how would it benefit Zencart website owners.

Best wishes.
