Call to a member function on a non-obj...

I keep getting this error in a hack i just installed (website welcome), the error is:

Fatal error: Call to a member function on a non-object in /home/blackmag/public_html/webwelcome.php on line 25

I then take a look at line 25 and it says:

PHP Code:

$getnewpost=$DB_site->query_first("SELECT count(*) AS posts FROM post WHERE dateline > '$bbuserinfo[lastvisit]'"); 


I've heard something about global $DB_site but i have no idea how to use that function.. as if I have never used it before.

Put

PHP Code:

global $DB_site; 


right before that line that's causing you problems, and try again.

add a ; after Gary's line
