Unable to Create Refund after updating PayPal for WooCommerce

Which gateway are you using specifically?

Not to hijack, I did also get a refund error from my staging server when testing 1.4.0 on Woocommerce 3.0.5 in sandbox mode. This was an upgrade of our production setup in a staging environment.

It gives the error “An error occurred while attempting to create the refund using the payment gateway API.” in a popup in the browser. This happens on each order I try.

Arefund with the stripe gateway processes fine.

My apache error log gives this when the error is produced:
`[Tue May 02 07:47:03.616226 2017] [:error] [pid 8395] [client 192.168.0.180:51867] The The “woocommerce_add_order_item_meta” hook uses out of date data structures and function is deprecated since version 3.0.5.

We just released a 1.4.1 update that should resolve this. Please take a look and let us know.

I can confirm that refund functionality is working correctly after applying 1.4.1 update.

Thanks! Looks like we do still have a couple of other bug reports we gotta get worked out. You’ll be seeing a 1.4.2 update soon.
