Hey George,
Thanks for reaching out to us!
I took a look at your site and noticed the issue with the navigation on the main “/events” page. I also noticed that overall the page doesn’t seem to load properly like the rest of the site. I clicked over to the month view “/events/month” and noticed that the menu works properly on that page.
Looking at the default list view, I see that there have been some customizations made to the templates. There potentially could be some errors with the PHP for the custom layout that is causing the navigation issue. Try turning on WP_DEBUG and see what errors are displayed on that page. This will show you where to go to resolve the issue.
Let me know if this helps.
Thanks!
