I'm facing this error while running Yoast's WordPress SEO plugin:
PHP Fatal error: Call to a member function get() on a non-object in /home/sabi1999/public_html/wp-includes/query.php on line 27
The plugin is working fine though. But it's preventing another plugin running properly. And when I check my error_log, the above error messages is shown.
Any help on this would be much appreciated.
