 * Immediately after activating the plugin I get the following warning:
 * Warning: Undefined array key “EUR” in /app/wp-content/plugins/computop-payments/
   includes/Gateways/AmazonPay.php on line 112.
 * I am using the current version.

 * Thanks a lot for this report – we will fix that with the next release. In the
   meantime, could you try to configure Amazon Pay to “EU”? Then this error should
   disappear.

 * We don’t use amazon pay and it is not active. It was “EU” by default, but after
   I saved the amazon pay settings, the warning disappeared.
