Managed to get rid of the errors by updating the extentions as well as the navwalker menu. I double checked the plugin extensions for woocommerce to make sure they were up to date. Weird how they weren’t being listed that was a update available. Checkout page wasn’t showing because of the force SSL certicate. I disabled it and hoping when I go live should work.
