I’ve just moved the site from the staging server to the production server, and my client hasn’t asked for this to be fixed. I’m sure it has to do with some of my custom CSS possibly conflicting somehow. It’s not a deal breaker.
Since it’s on the production server, I don’t want to allow access. If my client asks for this feature to work in the future, I will contact you and arrange to get you the HTML, but in the meantime, I will just leave it the way it is.
