We are running WP 3.4.2 and Version 3.1.2 of HTTPS. When we activate the plugin, products added to cart, just cause the cart to spin...and if we go to the checkout, we valid SSL cert (all green).
When we deactivate the plugin, the add to cart works as intended...we get the unsecured items SSL warnings.
The plugin also causes some CSS issues with the cart. It seems to cut off 50px of the top of header image for no apparent reason.
Any help would be greatly appreciated.
