We are currently experiencing some issues with our license validation servers. This means you may see the following notice when trying to validate your license key: “Sorry, key validation server is not available.” Although license keys cannot be validated, your plugins will continue to work normally.
Our developers are actively working to identify and solve this issue. We expect this to be solved in the next few hours.
Our apologies for any trouble this may cause. Thank you for your patience while we get things straightened out!
Best,
The Events Calendar Support Team
