Limitations

There are a number of limits set in VPCART that help reduce memory load and overheads.But if you have, for example, more categories than the limit set, you can simply change the value to one closer to the number you actually have in the shop configuration.

xmaxCartItems = 20	Maximum items in the shopping cart. Even if you set this value to more than 100, e.g. 150, VPCart will only allow a maximum number of items added into the cart to 100. For example, if you set this config “xmaxCartItems”value to200, for example, and your customer in the storefront adds 115 items into the cart, the customer will then see an error message saying, “*There are too many items in your cart*.” You may think that you already set the config to allow for a maximum of 200 items, but your customer will still be unable to add 115 items. This is how VPCart has limited, by default, the maximum limit to 100 items in a cart for performance reasons.
xMaxCategories=100	Maximum number of categories
xMaxSavedCarts=100	Maximum number of saved carts
xMaxFeatures=4	Maximum number of features per product
