You found e.g. Real Media Library and want to use it in multiple WordPress installations? Great that you like our work! Unfortunately, at codecanyon.net you can only purchase licenses for one domain. Therefore, you have to buy a separate license for each domain. You can learn more about the Envato Regular License in the knowledge base of codecanyon.net.
If you run several sites within one multisite for one organizational unit and one product (e.g. sports club and each department has its own site), contact us and we will find an individual solution so that you do not need a separate license for each site.
If you are an agency, for example, and have special requirements, feel free to open a support ticket at devowl.io, and we’ll be happy to help!
