    Hi,

    When using <!--nextpage--> and enabled debug, I saw the following notice:

    Notice: Undefined index: link_before in /public_html/wp-includes/post-template.php on line 888

    Notice: Undefined index: link_after in /public_html/wp-includes/post-template.php on line 888

    It belongs to WP core I guess.

    What is that mean? How can it be fixed?

    Thank you.
