[Plugin: Buddypress-Ajax-Chat] New Install Fatal error: Call to a member function

Hi

I just installed this this on a fresh install, and the following error came up ‘Fatal error: Call to a member function get_page_permastruct() on a non-object in /home/content/11/6372311/html/hbcyg/wp-includes/link-template.php on line 274’. Does anyone know what’s wrong?

Thanks in advance
