After extensive testing as to why my e-commerce shop using WooCommerce wouldn't work, I figured out there is a conflict with a plugin. After even more testing I narrowed it down to WPGPlus. If I deactivate just this plugin then WooCommerce works as it is suppose to. However, if WPGPlus is activated then when you have a product in your shopping cart and try to checkout, it never completes. Upon selecting your form of payment and clicking on Place Order, it merely reloads the page and places a 0 (zero) on the page?!
Not sure what's going on here put I definitely need WooCommerce more than I need the connivence of being able to cross post to Google plus.
I've also alerted the WPGPlus author to this problem.
