Hello All,
Misty I have read your suggestion.
First of all will let you know about how I install worpress and my test zen cart cart then what is the problem I am facing.

1) Here is the location of my wordpress /data/www/wordpress

2) Here is the location of my zencart /data/www/test_shop

3) I have created one database which has table of worpress and zencart.

4) the location of wordpress-config.php is in the zencart folder test_shop\includes\extra_configures\wordpress-config.php.

PHP Code:
define ('ABSPATH',$_SERVER['DOCUMENT_ROOT'].'/wordpress/'); 
I can see the side box of wordpress on my zencart shop but when i click on the link like about, Uncategorized... then it redirects me to index page . I cant see the wordpress posting and comments .

So please let me know where I am wrong.

Thx
