May I use rehub theme in multiple site? I’ve seen many person do it.
yes you can but for each individual website you have to purchase individual license. Envato each license for each individual end product (for example: website).
Brother I meant one license but using multiple site.I saw many people do it.
no, it is fully illegal and almost every themes will not give you permit to do it. theme will ask you purchase code for each website untill you will not register the theme license.
how much is it cost the new licence, for the second using of rehub theme
Same as the first one.
There is no technical difference - just to allow each to be registered to individual websites
