2 x Undefined index in pay_button.inc.php

Hi,

during development of our child theme we closely follow the guide at https://mikejolley.com/2013/08/13/keeping-your-shit-secure-whilst-developing-for-wordpress/ (which is especially important for financial and e-commerce stuff ??

Like in step one we have define( WP_DEBUG, true ) enable on the development machine.

This throws two errors which seems to be due to the paymill plugin. Here are the stacktraces:

Happens when we try to edit a static page (but probably also at other occurences).

I can send you the woocommerce status report by PM if you want or need it.
I don’t know if this is merely caused by the plugin or by another plugin and the caused consequences.
