When you install iDevAffiliate, you have a license key that will lock to the server you are installing into. That license key locks to the server name, server IP and installation folder and can only be run from that location. However, it is possible to use the same license key on a secondary location for testing/development purposes. Just use the same license key for your secondary install. Should you ever encounter an “invalid license key” error at the admin center login page, simply load …/admin/local_reset.php in your web browser to lock the license key to the current installation you’re trying to access (toggle back and forth as needed). This will allow access to both installation locations simultaneously for testing/development purposes.
