Member.php Error

When I go to email a member or AIM a member I get this error:

Fatal error: Call to a member function on a non-object in /home/virtual/site1/fst/var/www/html/forum/member.php on line 1494

The only recent hack I've done is a photogallery, and even though I deleted it, I still get this error.

This is the line:

  $profilefields=$DB_site->query("SELECT profilefieldid,required,title
                                  FROM profilefield
                                  WHERE hidden=0
                                  ORDER BY displayorder");

Any help would be appreciated!

you have made a mistake and removed the globalisation of $DB_site.

if you don't have hacked it anymore, just upload an unhacked file again

I got it fixed, apparently I had an extra } just above this line.
