I just updated to breadcrumbs 1.5.19 and the new wordpress build 5.7.1 and I now get an error message in the admin dashboard:
constant post_grid_plugin_url - assumed 'post_grid_plugin_url' (this will throw an Error in a future version of PHP) in /code/wp-content/plugins/breadcrumb/breadcrumb.php on line 76
Is there a way to eliminate this conflict? The line in question is:
wp_register_script('jquery.lazy', post_grid_plugin_url.'assets/admin/js/jquery.lazy.js', array('jquery'));
Welcome to our forum.
I have already fixed and updated plugin, please try latest version and let me know the result.
