Been testing the payment function, there are some test orders I made myself as a guest and a signed-in customer. But when I select Ship > Submit Shipment I get this error "Cannot save shipment.".
the error message in the exception.log is
[2017-05-26 06:06:55] main.CRITICAL: Exception: Rolled back transaction has not been completed correctly. in /var/www/cedweb.com/vendor/magento/framework/DB/Adapter/Pdo/Mysql.php:232
I've tried Truncate order tables but it won't help.
Any help would be much appreciated~
the whole log like the following
