I am getting an error approving a pingback but before I waste time trying to solve it, what is the use in approving pingbacks? Does it add a link to the referring article to my article or what? Just wondering what the use is here.
My specific error is
“Notice: Use of undefined constant WP_NETWORK_ADMIN – assumed ‘WP_NETWORK_ADMIN’ in /var/www/wp-content/plugins/google/lib/class_wdgpo_admin_pages.php on line 60 1319290630”
