I am now configure Zen Cart to work with phpBB.

I shop URL is (e.g)
http://www.myshopname.com.sg/shop

http://www.myshopname.com.sg/forum



After I edit the /includes/configure.php

define('DIR_WS_PHPBB', '/phpBB2/');
to

define('DIR_WS_PHPBB', '/home/myshopname/public_html/forum/');


I can see the Forum link at eshop.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
