 * Hello,
    I currently receive the following error on my webinar registration page:
 * `Warning: Undefined array key "gotowebinar_enable_timezone_conversion" in /var/
   www/vhosts/pjmueller.de/beta.geldhochschule.de/wp-content/plugins/wp-gotowebinar/
   inc/shortcode-registration.php on line 224`
 * I guess the problem is PHP 8.0, but I am not 100% sure.
 *     ```
       PHP Version: 8.0.14
       Wordpress Version: 5.8.3
       Plugin Version: 14.30

 * Hi [@pixelprinzip](https://wordpress.org/support/users/pixelprinzip/),
 * I will release a fix for this in the next version. In the mean time you can change
   that code to include an additional check like so:
 *     ```
       if(array_key_exists('gotowebinar_enable_timezone_conversion',$options)){
                       if($options['gotowebinar_enable_timezone_conversion'] == 1){
                           $html .= '<p><a class="timezone-convert-link-registration">'.__( 'Convert to my timezone', 'wp-gotowebinar' ).'</a></p>';
                           $html .= '<span id="timezone_error_message" style="display:none;">';
   
                           if(isset($options['gotowebinar_timezone_error_message']) && strlen($options['gotowebinar_timezone_error_message'])>0){
                               $html .= $options['gotowebinar_timezone_error_message'];     
                           } else {   
                               $html .= 'Sorry, your location could not be determined.';
                           }
                           $html .= '</span>';     
                       }
                   }
       ```
   
 * Or alternatively you can just turn off PHP show errors in your wp-config or hosting
   configuration. The error itself is non-consequential, that is, apart from the
   visual display it doesn’t actually affect anything. Thanks,
