Rather than keep patching, we suggested moving the whole shop over to WooCommerce, and we offered to redesign it at the same time. We worked to a minimal budget, because helping the client get something affordable was our priority for a business just starting out. There are no bells and whistles. Instead, the new shop has a better layout, makes better use of space, works properly on mobile and is simple for the owner to run day to day. Most importantly, it actually works.
