Well it's working now, but what come up is an other problem in case I do try to change Status. Actually I can't, because otherwise come a page says this :
In fact if I don' type anything into the Comments, the page just refresh and say that is updated, but it not. And if I try to type something into the Comments then become that Error.
1054 Unknown column 'track_id1' in 'field list'
[INSERT INTO orders_status_history (orders_id, orders_status_id, date_added, customer_notified, comments, track_id1, track_id2, track_id3, track_id4, track_id5) VALUES ('1', '3', now(), '1', '', '', '', '', '', '')]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.
Any idea ?
