 * Hello,
 * Thanks for your great and very useful plugin!
 * I got the following message since latest update of WordPress:
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, class‘
   cf7_sendpdf’ does not have a method ‘init_l10n’ in /home/myserver/domains/mydomain.
   com/public_html/web/wp-includes/plugin.php on line 525
 * When I deactive your plugin then warning disapear. Can you please help me to 
   fix it?
