When installing an app, theme or when downloading phpFox you are asked to enter your sites License ID and Key. This information is emailed to you when you first purchase a license. If you have lost this information you can retrieve from here.
If you are running Neutron (v4 or higher) you can access your sites license information by opening the file /PF.Base/file/settings/license.sett.php.
In that file you will find something like:
define('PHPFOX_LICENSE_ID', 'c5daa43d32eabb6da3e3ad6966ffa87d'); define('PHPFOX_LICENSE_KEY', 'f353c6edf0293240a372d7876f27832f'); |
The 32 character jumble of letters and numbers is your license ID and Key.
