 * Hi guys,
 * I installed your plugin and put this shortcode _[qrcodetag\_from\_goaskle\_com/]_
   into email template. When I placed an order I see on the final page bellow this
   text:
 * “**Warning**: Undefined array key “wc_data_template” in **/www/doc/www.hochwasserohnesorgen.
   de/www/wp-content/plugins/qr-code-tag-for-wc-from-goaskle-com/lib/qrct/QrctWp.
   php** on line **1414**”
 * QR code is visible and under it is text with this issue.
 * It is related with your plugin. What is the problem, please?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwarning-undefined-array-key-wc_data_template%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hello!
 * Thanks for you report. Just fixed in new version 1.9.27. Please update and let
   me know if any errors will be found.

 * BTW. For standard Woocommerce you do not need to insert shortcode in templates.
   It is done using hooks in code. So just enable plugin and QR code must shown 
   in all emails ( if you did not changed any plugin settings ).
