Hi,
Thanks for the report.
We added a patch in HikaMarkt 1.7.3 for that missing ACL ( order/edit/vendor ).
You can add manually the ACL in the "administrator/components/com_hikamarket/type/market_acl.php" file by adding the entry
in the order edit array.

By the way, do not send me private message, use the "contact us" form instead.
