 * Hi,
 * since upgrading to all latest WP, Woocommerce, Plugins, themes and finally to
   php7, I found a new menu in admin > plugins > plugin licenses.
    going to this
   menu item does bring an error message: `Warning: call_user_func_array() expects
   parameter 1 to be a valid callback, function 'edd_sample_license_page' not found
   or invalid function name in /some/path/to-my/site/wp-includes/class-wp-hook.php
   on line 298` I did a grep for edd_sample_license_page in my plugins folder which
   found one occurence of ‘edd_sample_license_page’ in wp-product-feed-manager/includes/
   user-interface/wppfm-admin-menu.php:148
 * So far it seems not to affect my sites functionality. So just for your information
   only!

 * Hi Tom,
 * I see I also have this error message when opening that menu, so that makes it
   a lot easier for me to debug :-).
 * Thanks for reporting, I will put it on my fix list.

 * Tom,
 * I fixed this error. The fix will be implemented on the next update of our plugin.
   Again thanks for reporting!
 * Best regards,
    Michel
