I used WP Ultra Simple Paypal Shopping Cart. When I add an item and them try to delete it from the cart I get - Warning: Invalid argument supplied for foreach() in /home/content/p3nexnas05_data03/59/2166859/html/wp-content/plugins/wp-ultra-simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 152
I've now tried 2 other plugins and get the same error (different line numbers). I'm guessing it is theme related since it is happening with multiple plugins.
I reposted this issue because it was mixed with another issue that got resolved. It turns out this is still an issue.
