I have purchased a theme twice for 2 domains. I would like to reinstall the theme again on the same domain, but how do I know which license I purchased for that domain ?
You need to purchase a license for each time you implement the theme. This does not include re-installing the theme, but for each different project.
For example we sell a one pager theme for WordPress which allows you to make landing pages. Some of our users want to build landing pages for different projects, that means they need to purchase a license for each project.
So basically this would mean a license for each project: www.website.com www.website.com/another-project/ project-c.website.com/
Hope this helps.
