After adding to cart - Products cant be viewed - Nav Issue(?)

[anthwinter]

Hi,

 

So i'm moving a osCommerce shop to another server. Everything's looking to be OK but after adding items to the cart, then going back to try and view more products, things go wrong.

 

URL: www.allureaspect.com

 

I've added items to the cart. Then I click on, say, "Business Cards" down the left nav. Then when clicking on the price of a product on that page, to view the product, it then takes me back to the homepage.

 

The session is not being lost because the items are still in the cart.

 

My initial thought was that it maybe because after adding to the cart, then clicking the links down the left nav stopped displaying the osCsid in the URL.

 

If i use the "Continue Shopping" button after adding to the cart, i can keep adding multiple products. It just seems to be when yo use the left nav.

 

Can anyone help?

 

Left nav code:

 

        <ul>
               <li><?php echo '<a href="' . tep_href_link('step-1-businesscards.php') . '">Business Cardss </a>'; ?></li>
            <li><?php echo '<a href="' . tep_href_link('letterheads.php') . '">Letterheads</a>'; ?></li>
            <li><?php echo '<a href="' . tep_href_link('compliment_slips.php') . '">Compliment Slips </a>'; ?></li>
            <li><?php echo '<a href="' . tep_href_link('BusinessForms.php') . '">NCR Sets, Pads, Books</a>'; ?></li>
