I'm running out of ideas, wondering if anyone can help or has had this problem...
So any global attributes (Products->Attributes) that I create after WP 3.5 update will not display on the front end. All attributes that I had before the update work as normal. Also, any new "Custom Product Attribute" created through the "Edit Product" pages work fine and are displayed in the frontend.
I should mention that I updated both WP & WooCommerce around the same time and that I did not discover this issue until I purchased and installed the "Variation Swatches and Photos" (http://www.woothemes.com/products/variation-swatches-and-photos/)
plugin. I've already tried de-activating and removing the plugin.
WP 3.5, WooCommerce 1.6.6, Custom Hatch Theme, Variation Swatches and Photos 1.1.1
