10. Issue: please provide your purchase code in configs/env file

If you are having trouble building the FluxStore source code and are receiving a warning message that says "please provide your purchase code in configs/env.xx" try the following

Solution:

First, double check the envatoPurchaseCode located in the configs/env.props file and make sure it matches the license key file. You can find more information about where to locate your purchase code in this Where is My Purchase Code? article.

If you previously activated your license key on an old domain site and are now trying to run it on a new domain site, you may encounter issues. To resolve this, log in to your Wordpress site, go to MStore API, and select "Deactivate" next to the license key, or select "Deactivate" from the FluxBuilder app.
