Parse error: syntax error, unexpected '*' UPGRADER

 Parse error: syntax error, unexpected '*' in /home/livindea/mackforums.com/includes/functions.php on line 1433 

I am getting the above parse error when attempting to access the upgrader from vBulletin 3.8.7 to upgrade to 3.8.11. The following is on that line in /includes/functions.php:

            if (intval($profilefield_value) & (2**$key)) 

Could I get some support with this please?

Thanks!
