Does not work with WooCommerce

This plugin caused an error which effectively disables the “add to cart” button.

The problem: This plugin just takes a bunch of script tags in the head tag and relocates them into the body tag with the defer attribute. That might be okay if they were using JS promises or something similar, but I don’t know if you can implement a solution with single plugin. There are too many unknowns to just relocate scripts tags in this manner. WordPress already lazyloads images by default, so there isn’t a lot of upside to using this plugin.

If you plan to use plugins that rely on jQuery, it may cause problems for plugins other than WooCommerce.
