This error message appears when you have not setup the product pricing slabs you offer with WHMCS in your LogicBoxes Reseller account -> Settings -> Manage Products and Pricings -> "Service or Product Name" -> Manage Price
By default, only 1 pricing slab is set eg. for Reseller Hosting Linux product only the 1st Month price slab is created. If you offer 3, 6, 12, 24 and 36 Months with WHMCS, then you have to setup these pricing slabs too. The selling prices does not matter in you resellerclub account but you have to activate these slabs.
