Keep Cart v2.0.3 is now available: https://www.zen-cart.com/downloads.php?do=file&id=992

It's been tested on zc157c and zc158 and requires a minimum of PHP 7.3 to be enabled.

This release contains changes associated with the following GitHub issues:

#8: Correct 'occasional' PHP warnings during cart-restoration from cookies.
#9: Log configuration errors only once per storefront customer session.
#10: Ensure that cookies are removed when the cart is emptied.

Please note, this is now considered the plugin's support-thread!
