Menu not working on wordpress blog posts on iphone

[millo2k]

I have a weird issue I could do with some help with...

I have implemented the menu for this wordpress site: http://bs-14-001.barefacemediaprojects.co.uk/

Works great - thanks for the effort into this.

However, when you click on a case study: http://bs-14-001.barefacemediaprojects.co.uk/the-hyde-group/

The menu doesnt respond on touch. Really don't know why this is happening! Any ideas?

Thanks

Forgot to add this seems to be an iphone 6 issue
