It appears that Apple’s latest upgrade to their iPhone operating system does not play nice with mobile WordPress sites.
After upgrading my iPhone 5 to iOS 7, I noticed that the mobile versions of some of my websites didn’t display properly anymore; the page did not fit in the width of the screen and it had horizontal scroll bars.
I use two premium mobile plugins for various sites – Mobile by iThemes and WPtouch Pro by BraveNewCode. When I realized that both of these plugins had the same problem, it became clear that it was a problem within the device, not the plugin. Viewing the desktop version of the sites would also have the same problems, and even using the Chrome browser had the same problem as Safari.
I submitted support requests to both iThemes and BraveNewCode for their respective plugin, and each have confirmed the issue.
Hopefully Apple will come up with a solution soon. Check back for updates on this issue.
