Im stumped and luckily i had a backup with 4.2.2 version. But on the homepage i have a image background for mobile only . Two buttons slide in from outside on both computer and mobile version but when you update it makes the buttons disappear on mobile and creates a blank link.
I have looked at your homepage and see you have v4.2.3 installed now and the buttons are sliding in and the buttons are working on Android. Has your web dev solved this issue, or is this only happening on iPhone?
