If you’re unable to activate your license key on your website then there could be a few reasons why:
1. The license key you’re trying to activate is invalid
Make sure you’re not accidentally trying to activate your purchase key or invoice key. Your License key is listed within your Account and also emailed to you when you first purchase the plugin.
2. You’ve exceeded the number of sites that your license can be activated on
If you have a Personal (1 site) license then check to make sure it isn’t already activated on another domain, such as a staging or test/development site. If you have a Business (5 site) license then it’s possible that you have already activated the license on 5 other domains. You can check the sites that a license is activated on in your Account.
3. Something may be blocking your website from connecting to ours to verify your license
If you’re still unable to activate your license key on your site then it’s likely that something on your site/server is blocking the connection from your site to ours. 99.9% of our customers are able to activate their licenses without a problem, but for a select few people there seems to be a problem activating, usually due to a security setting on their server.
You are usually able to solve the problem by having their hosts add our website IP address to their outgoing firewall. Your host may have an IP defined outgoing firewall in place on their server and so adding our site to it will then hopefully allow you to activate your license key successfully. Try asking your web host to add our site to their outgoing firewall:
