 * Hello, I have gotowebinar connected to my site. The registration form is also
   displayed, but I also get the following error. (**Warning**: array_key_exists()
   expects parameter 2 to be array, bool given in **/home/www/huckauf/wp-content/
   plugins/wp-gotowebinar/inc/shortcode-registration.php** on line **224**)
 * What can this be?
   Thank you

 * Hi [@landfair](https://wordpress.org/support/users/landfair/),
 * This error would normally show if the settings haven’t been saved yet. Have you
   saved the settings? Is the error persistently shown on the page or did you just
   see it once in an error log? If it is just in your error log, don’t worry about
   it, this is just sequence issue.
 * If the error is persistent, can you send me a link to the page with the shortcode.
 * Thanks,

 * Hello, yes, unfortunately the error message is displayed permanently. Where can
   I send the link?
 * Best regards
