Product List is showing out of stock item

[asgc]

Can someone help.

 

I tried to inactivate product on the website, and i have turn off at the catalog/admin but under the website product list, it's still showing as normal.

 

Once i click on the out of stock product link, it will link into the product with showing $0

 

But i want this product to be turn off directly instead of showing.

Choose the 1st one CM.030 Glock 18C Semi-Auto Electric Gun <== should be the out of stock but still showing at here

 

I got a friend to help to edit but he couldn't solve the problem.

 

Which file should i edit or change?

 

Thx
