I have a site that uses a responsive WordPress theme. The other day, we noticed the iPhone menu doesn't allow you to scroll to any of the other pages, as if they don't exist:
We've checked it on more than one iPhone (we haven't checked it on Android). The menu works fine on a desktop, and the menu structure is completely intact in WordPress.
On the first of May, the hosting company upgraded to the current version of PHP, saying that if we "happen to notice issues" we can revert to the previous version of PHP. I can't see how PHP could affect a responsive website, but it's the only variable in the equation.
iPhone issue? PHP issue? Wordpress theme issue? I'm stumped. Any ideas?
