 * Hello! I was very happy to see that you came back to developing and supporting
   this plugin. Thanks for the great work.
 * When Gravity Forms are submitted, I am getting this warning message:
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, function‘
   wpzerospam_gform_validate’ not found or invalid function name in /home/theabcn6/
   public_html/wp-includes/class-wp-hook.php on line 289
 * Please advise. Thank you!

 * Thank you! I just installed the update. Unfortunately, right after activating
   the plugin, I am now getting a different warning:
 * Warning: Use of undefined constant REFERRER_ANALYTICS – assumed ‘REFERRER_ANALYTICS’(
   this will throw an Error in a future version of PHP) in /home/theabcn6/public_html/
   wp-content/plugins/zero-spam/inc/scripts.php on line 17

 * Incredible. Amazing support. Super responsive. If you’re feeling ambitious, please
   find a cure for the novel coronavirus. I bet you could!
