I installed the Advanced Free Shipping for WooCommerce plugin on my e-commerce site a few months ago, and it worked fine until today, after a customer reported it. I noticed that, even though I hadn’t made any changes to the plugin, the shipping option no longer appears at checkout. I tried making some small changes and uninstalling the plugin, but the problem persists. I currently have free shipping set for orders under 15 kg and a subtotal of over 150 CHF.
