We’ve made a small update and released WooCommerce 2.6.6 today to fix a potential conflict with extensions. You can download it on WordPress.org or as an automatic update in your administration panel.
Only ~2 made it into this release to fix:
- A conflict with Local Pickup Plus due to 2.7.x code making it into the 2.6.x branch. This went unnoticed due to core not using the function with the error.
- The sort order of shipping methods was not being respected on the cart.
If you spot any further issues, please report them to us in detail on GitHub so the development team can review – comments on this post are closed.
