 * It is quite strange that two of this client’s galleries have this problem, but
   the others don’t.
 * <b>Notice</b>: Undefined index: thumbnail in <b>…/wp-content/plugins/modula-best-
   grid-gallery/includes/public/modula-helper-functions.php</b> on line <b>354</
   b><br />
    <br /> <b>Notice</b>: Trying to access array offset on value of type
   null in <b>…/wp-content/plugins/modula-best-grid-gallery/includes/public/modula-
   helper-functions.php</b> on line <b>354</b><br />

 * Hi [@marjoriesdaughter](https://wordpress.org/support/users/marjoriesdaughter/),
 * Thank you for reaching out to us!
 * I’m sorry about this! We opened a ticket regarding this and we will fix it in
   our future update. Here is the ticket so you can see the progress: [https://github.com/WPChill/modula-lite/issues/611](https://github.com/WPChill/modula-lite/issues/611)
 * It seems that this is happening when you use Smush CDN. You do not need to worry
   because they are only notices and in order for them to not appear anymore please
   go to wp-config.php and to Disable WP_Debug, change this line to: define( ‘WP_DEBUG’,
   false ).
 * Please let me know if you have questions!
 * Warm regards,
    Beatrice.
