[Fix] Conflict post_type product

Hi,

I’ve been using this plugin for one of my sites, and after the last updates I could use it on my custom post type “product”.

It seems you’re checking this because of woocommerce.
I’ve fixed it for myself by checking it like this:

$is_woocommerce_product = ($post_type == 'product' && class_exists('Woocommerce'));

and using that variable instead of “product” == $post_type.

Can you “fix” this in the next release?
