Thanks...")* Hello, There is no more "JArrayHelper" in the plugin since October 2018 and the release of HikaMarket 3.0.0 All "JArrayHelper" have been replaced by internal functions from the HikaShop/HikaMarket cores. [ www.hikashop.com/support/documentation/1...arket-changelog.html](https://www.hikashop.com/support/documentation/147-hikamarket-changelog.html) But the plugin "Shipping Fee Per Vendor" is not part of HikaMarket since it's a custom plugin ; which has been updated in 2018 like the rest of the HikaMarket eco-system. Please replace the Code: JArrayHelper::toInteger($shipping_ids); By Code: hikamarket::toInteger($shipping_ids); Regards, --- Jerome - Obsidev.com HikaMarket & HikaSerial developer / HikaShop core dev team.
