Hi,
Thanks for reaching out to us! I’d be happy to help you.
Your PRO License is valid. However, looking at your System Information, it seems The Events Calendar PRO plugin is not activated on your website. Can you check if the plugin is well installed and activated?
Also, I notice you have a version of WordPress which is slightly outdated. For security and performance reasons, I would recommend to upgrade from 4.7.5 to 4.9.5.
Please let me know if you still encounter difficulties after those manipulations.
Cheers,
Jeremy
