Hi,

i messed things up somehow. I fixed some errors but still have the following:

1. In the "index.php" page of the catalog under "Categories" I get this error: 

Warning: Invalid argument supplied for foreach() in /home/j007w/public_html/catalog/includes/modules/main_categories.php on line 50

This is the "main_categories.php" starting with line 49
[code]// Traverse category tree
    foreach ($foo as $key => $value) {
      if ($foo[$key]['parent'] == $cid) {
//        print "$key, $level, $cid, $cpath<br>";
        preorder($key, $level+1, $foo, ($level != 0 ? $cpath . $cid . '_' : ''))
;
      }
    }
  }

?>
<!-- main_categories //-->[/code]

2. In "product_info.php" of the catalog I get the following error in every product:

Fatal error: Call to undefined function: in_cart_mixed() in /home/j007w/public_html/catalog/includes/functions/quantity_controller.php on line 295

This is "quantity_controller.php" starting on line 288

[code]// Return quantity buy now
  function tep_get_buy_now_qty($product_id) {
    global $cart;
    $check_min=tep_get_products_quantity_order_min($product_id);
    $check_units=tep_get_products_quantity_order_units($product_id);
    $buy_now_qty=1;
    switch (true) {
      case ($cart->in_cart_mixed($product_id)==0):
        if ($check_min >= $check_units) {
          $buy_now_qty=$check_min;
        } else {
          $buy_now_qty=$check_units;
        }
        break;
//      case ($cart->in_cart_mixed($product_id) < $check_units):
      // not used - decide how quantity should be handled
//        $buy_now_qty=$check_units;
//        break;
      default:
        $buy_now_qty=$check_units;
        break;
    }
    return $buy_now_qty;
  }[/code]

3. In the admin section, when I click on either of the 2 links in "Paypal IPN" box or a link to any products in the drop down box on the upper right corner in "Catalog" it takes me back to the login screen. When I log in again it takes me back to the "My Store" in "Configurations" box. 

Thanks in advance; I really appreciate it.
