error 127 from table handler

Sorry it's late and I'm just posting this before bed.

I've just started to receive this error when accessing members details.


Got error 127 from table handler
in query:

SELECT u.*, SUM(if(p.completed, 1, 0)) AS count_of_completed, SUM(if(p.completed, p.amount,0)) as summa_of_completed FROM membership_members u LEFT JOIN membership_payments p ON (p.member_id=u.member_id) WHERE 1 GROUP BY u.member_id HAVING 1 ORDER BY u.login LIMIT 0, 20

I've had a quick look but cannot see it anywhere


Regards

John
