LOCATING YOUR KEY
When you purchase the Duplicator you will receive an email with your license key. Be sure to check your spam folder if you don’t receive an email within a few minutes of purchase.

You can also get your license key(s) by logging into your Duplicator Account. The user name will be the e-mail you used to purchase the product. If you are unable to retrieve your password when logging in, please submit a help ticket.

ACTIVATING YOUR KEY
Activation is very simple.

1. Download, install, and activate the plugin from your purchase email link or from your Duplicator Account.
2. Goto: Duplicator Pro > Settings > Licensing > Enter your key and click activate.

Solution 1 Validation: Log in to your Duplicator Account. and check the license key number and validate your license count. If your key is valid and you have the proper count, then proceed to the next step. If your license has expired then you will need to renew it. If you have maxed out your license count, then you will need to remove a registered URL or upgrade your product to support additional licenses.

Solution 2 Activation: Activation requires a connection to the duplicator.com servers; in some cases, cache plugins or even web server caches can cause issues. In these cases, try the following options:

1. Try deactivating and reactivating your license a few times, waiting a minute or two between tries.
2. Deactivate & reactivate the plugin from the WordPress admin plugins screen, then try the key activation again.

• Networking: Check with your host to see if their servers can reach https://duplicator.com
• Contact Host: Contact your host or server admin and ask them to monitor what happens when you click the license activate button. Specifically, ask if communication is blocked between your server and duplicator.com. If they observe nothing getting blocked on their side, then proceed to the step below.
• IP Checks: Gather the following IP addresses by going to WordPress Admin > Duplicator Pro > Tools > General Tab > Server Settings > “Server IP”, “Outbound IP”, “Client IP”. If any are blank, then contact your host or system network administrator, as it’s located at the router layer, and we must have all of them in order to properly diagnose the issue from our end.

  Note: If you are a localhost server, you may see “::1” for “Server IP” and “Client IP.” If this is the case for localhost then providethe “Outbound IP”.

  Once you have all the IPs, submit a ticket or reply to an existing ticket with all IP addresses. We will then check to see if they are being blocked on the duplicator.com end. This is typically very rare, although it can happen if your server’s IP has been placed on a blacklist of some kind.
