Hey Kevin,
Thank you for reaching out to us! As I can see from your system info you only have The Events Calendar installed and activated: you have to install Events Calendar PRO to be able to use the shortcodes.
Please access your account, download and install the latest version of Events Calendar PRO.
After that, please access your Dashboard and head over to Events > Settings > Licenses, add your license key and press the “Save Changes” button in the end of that page.
I hope this helps!
Let me know if you need anything else in the mean time.
Best Regards,
Patricia
