1364 Field 'oc_note' doesn't have a default value

[GJC Web Design]

maybe find another host that doesn't enforce strict?.. 

the error is explained here:  https://stackoverflow.com/questions/36374335/error-in-mysql-when-setting-default-value-for-date-or-datetime

but if the host wont help with this by disabling then a core hack will probably be needed

perhaps in administrator\components\com_virtuemart\tables\orders.php

change line 102 to

var $paid_on = NULL;



but this may break some logic further down the track
