Warning: Use of undefined constant RPPostNav

  • Not sure when this started or what triggered it, but I’ve been getting this error message:

    Warning: Use of undefined constant RPPostNav - assumed 'RPPostNav' (this will throw an Error in a future version of PHP) in /var/www/vhosts/robinverdegaal.nl/httpdocs/wp-content/plugins/rp-post-nav/rp-post-nav.php on line 41

    What could be causing this?

    WP 5.5.1
    PHP 7.3.21

    The page I need help with: [log in to see the link]

    Forgot to mention: the same error displays on another wordpress install, same PHP version, on both WP version 5.2.7 and 5.5.1. That site is not https like the site from the issue, so that can’t be the culprit either.
