Reasons for your license not to work
Why my license isn't working?
Many users ask us this question after making a purchase, setting up the software and testing it. Then they would try to use the software on their domain and they get the error: “Please insert here the license for your theme.”
What really happens is that the user makes a purchase of one Pro license, which comes with one license that can be used on only one domain. So, one license = one domain and can be used as many sub domains as you want. Then they would use that license on their localhost or on a test site just to see how the theme is working and when they try to get the theme working on their main website they face this issue.
