Wishlist sharing urls not working

Afternoon Team LH,

I've just noticed that wishlist url's that I've just tried to generate aren't working. I've tried twice, but each time get a 'Sorry, something bad has happened, We are distraught! If you can see this message something's not right on LoveHoney.' error page.

The title of the wishlist does get displayed in the page's title though. Some script error?

Here's an example url:

Just thought I'd give you guys a heads up, I hate finding errors on my site(s) and wondering how long they've been happening for!
