I used this code at local host and it was registered . Now i moved to my hosting and again setting up site on subdomain and getting that error “Code is already registered for other domain”
In this case you have to deregister the license from the localhost and have to register for the live website. If you don’t have option to deregister the license then you have to contact the item author and let them know they will assist you.
