I just tested your code, but to do so I had to remove your if condition because there's no DO condition like that on my system and there's no 'active_users_onoff' that I know of in a standard vB4 install.

So I ended up testing this...

PHP Code:

   $first=true; 
    foreach ( $activeusers as $row ) { 
        if ( $first )    {  
            $first = false; 
            $str = "<li><a class=\"username\" href=\" \"> " . $row["musername"] . "</a></li>";    } 
         else {  
            $str .= ",&nbsp<li><a class=\"username\" href=\" \"> " . $row["musername"] . "</a></li>";    }            
     }     
    echo "<p>" . construct_phrase($vbphrase['users_currently_browsing_x_y_z'], $totalonline, $numberregistered, $numberguest) . "</p><ol class=\"commalist\">" . $str . "</ol>" ;
     exit; 


It worked fine with IE.

The other question I have is why not just use the 'Show Users Browsing Threads' option that's built in to vB?
