Worked for me, although initially highlighted another @strpos error in the functions.php script.

However setting is bozo to 1 in the admin pages creates the appropriate row in the meta table for the user, setting it back to zero deletes the row, rather than setting the value to zero (which is presumably why the box remains blank) while it works, it seems an odd way of doing it!

(Just realised I am being critical of someone else’s work without the ability to do it better myself – my apologies – I suppose I ought to get down a book on PHP and try and actively contribute rather than just fault find…)
