I've merged these two topics as it's in regards to the same issue. We're still looking into this and don't have a reason for the cause yet. We've disable CBs jQuery entirely, CBs CSS entirely, and the issue is still present so I have no idea what's causing this. It's limited to iPhone and iPad devices only (all browsers). I don't know if it's just a bug in the device or what, but why CB triggers the issue is what is the most confusing part as even if the only thing loaded by CB is the HTML for its login module the issue is still there, which makes no sense.

What I meant is on our test site we have just the login module present to provide a very minimal environment. The issue persists even if we force CB to basically load nothing. So only CBs PHP and the HTML of the module it self are loaded on the page. No CB jQuery and no CB CSS present. Yet even with such a minimal environment the issue persists, which again makes absolutely no sense.

We've made it even more minimal by using the CB Online module which is nothing but a UL element that's empty, no CSS loaded, and no jQuery loaded (or JS for that matter) yet the issue also persists.

I'm guessing CB is causing Joomla to load something that normally isn't loaded by default. I've yet to find out what though as am still looking into this.
