Hey Ferol,
Thanks for contacting us!
Did you include your Event Aggregator license key in your WordPress install? From your WordPress dashboard, please head over to Events → Settings and select the Licenses tab at the top of the screen.
You will see a License Key field for each activated plugin that requires a license key. Please copy your key from your license page and paste it in the correct field. It should show a green “Valid Key!” message underneath. Once you see this message, click the “Save Changes” button to register your license.
You will find further information in our KB:
Finding and Inputting Your License Key
I hope this helps! Let us know if you need anything else and have a great weekend!
Regards,
Patricia
