To use the premium features of the WP Activity Log you need to activate the license key. During activation, the plugin communicates with the below URLs to confirm the validity of the license key:
If your WordPress website and plugin are installed behind a network firewall with no internet access, just white-list the above mentioned URLs to activate the license key. For optimum security you can also restrict access to these URLs to just the web server on which the plugin is running.
No firewall / internet connection exception?
If you cannot allow access through the firewall or your website is completely isolated from the internet please contact us. We have an edition of the plugin which does not require any license activation that is available for prospects who need at least a 50-site license key.
