Problem with Swagger

After updating to WordPress 4.4, my website’s menus take the user back to the homepage. Is anyone else experiencing this? The website in question is http://rantaboutfilm.com

The consensus across various formus is that the issue is with the theme, Swagger. I’ve used Swagger for years, and I’d hate to switch to something else. Is there a way to fix the menus and stay with the theme?

I’ve created a new menu to see if that would work, however, it behaves the same way as old menus.

I’ve also changed the permalink settings to default. Neither solution works.
