For now, this plugin is incompatible, have some bugs and can´t be used, soo sad, please fix
A big NO to Refiral. Incompatible with any version of CS-Cart . Refiral Support teams doesn't know anything about CS-Cart. We have been waiting from last 4 months but till date haven't been on-boarded. Would recommend CS-Cart to review such products/addons before bringing them to marketplace.
