For some reason, when i do a query to the database within this page i get the following error
"Fatal error: Call to a member function on a non-object in /vservers/lustiesn/htdocs/vbulletin/main.php on line 45"
and there is the code that i'm using to query to the database

PHP Code:

 $getnews = $DB_site->query_first("SELECT * FROM thread left join post  on (post.postid=thread.firstpostid) where thread.forumid=18  order by thread.threadid desc limit 1");
