Howdy Gary,
I would love to help you with this.
It sounds like your site is probably throwing an error but not set to display them publicly. Typically the page will either be a blank white or it will stop loading half way through. Could you set WP_DEBUG to true in your config file? More detailed instructions are in that link. From there try loading this page again, does it show an error message with Pro active? What’s the message?
Also would you mind grabbing your system information and pasting it here? Make sure to use the ‘Set as private reply’ checkbox to protect your private information from the public. You can find the system info by going to WP Admin > Events > Settings, clicking on the “Help” tab, and scrolling down to the ‘System Information’ box. (Or by going to [yoursite]/wp-admin/edit.php?post_type=tribe_events&page=tribe-events-calendar&tab=help) That will give me a lot of extra information to help diagnose the problem.
Cheers!
