I ran auto-upgrade from 2.7.1 from admin panel and now when I login to admin, I receive the following error:
Fatal error: Call to undefined function is_site_admin() in /home/theledli/public_html/Simon/wp-content/plugins/wordpress-related-posts/related-posts.php on line 81
A quick trip over to the specified line reads:
if ( !function_exists('get_site_option') || is_site_admin() )
How can I resolve this?
Can I downgrade?
