Hi @eberling, 🙂
You can easily add a link to a website to redirect your user to it. Please find the attached screenshot.
Maybe these articles form The Events Calendar documentation will help you as they seem to answer the same concern:
Please note that this issue is related with the use of a third party plugin, not with the use of your theme. As theme authors, the installation, setting or debugging of third party plugins isn’t part of the support we will provide.
To go further, we invite you to ask for more help from the plugin authors and post your request on their support forums: The Events Calendar support
We remain available for all support requests related with the use of your theme.
Regards,
