Broken functionality

Hi there,

I have used your handy plugin and it works really well. But it somehow has broken our functionality in another plugin where we use wc_get_product_id_by_sku() and add_product_to_cart() functions to add product in the cart based on a sku?

Instead of adding the product in the cart, it takes user to the product page. Above functionality works successfully if I deactivate your plugin.

Any idea why this would be?

Thanks,
