Not Compatible with Woocommerce 2.1.0

Customers experience “Invalid shipping method” upon check-out. Then unable to proceed with transaction.

This is my error message:

Warning: array_intersect() [function.array-intersect]: Argument #1 is not an array in /home/checkmy/public_html/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-shipping-method.php on line 179

Yes, this is most unfortunate as we really love your plugin Andy! Please update it for us, thanks so much for your great work!

Guys and gals, I just found a suitable replacement for this:

That plugin claims it was based on this one, but is updated and works with the new WooCommerce. I’ve switched, it works perfectly, I suggest you do too as this one sadly isn’t updated any more.

Thank you so much harryduns! I have done as you suggested and works perfectly. Can’t thank you enough.

Thank you thank you JeriffCheng for this fix – works perfectly – thank God!

harryduns – also thanks for the possible alternative – good for future sites.

same here, broken after Woo upgrade so am checking out the replacement plugin, shame as this was nice but no good any more 🙁
