Hello There,
Thanks for updating in! I can confirm that this is a bug. The notice is displaying in the breadcrumb specially if you have enabled the debug mode. If you wish to get rid of the PHP notice, please disable the debug mode. You can do this by opening wp-config.php and adding define( 'WP_DEBUG' , false );
just above /* That's all, stop editing! Happy blogging. */
For example:
define('WP_DEBUG', false);
/* That's all, stop editing! Happy blogging. */
When you revisit the page, you should no longer be seeing the notice. On the other hand, if you wish to correct the certain block of code, since your child theme is already set up, please add the following code in your child theme’s functions.php file
// Breadcrumbs
