Our home page link http://www.renaissance-singers.com/ returns a 404 Page not found error, and does this ONLY on Mobile devices.
I have searched all the WordPress.org support forums on similar problems and found no solutions. Any help would be appreciated.
I have tested our site http://www.renaissance-singers.com/ on all the major browsers on my desktop and it works fine. We use the standard Twenty Eleven theme with no child themes.
All our other pages and posts work fine on the mobile devices.
Only the home page is 404 page not found when viewing it on a mobile device (my Android's standard browser, a friend's iPhone). The favicon does not even appear (our BlueHost hosting service favicon appears instead).
I have tried adjusting our home page Settings > Reading from "recent posts" to "static page" and the error happens using both settings. I've re-saved our year-month-title post permalink settings (without changing them).
I have tried disabling all the plugins, clearing the mobile device's cache and browsing history, and it still happens.
In Google Webmaster Tools it shows nothing wrong with our site.
I have tried installing plugins "404 Redirect" and "WPtouch" and they do not resolve this problem.
It used to work a few weeks ago and I'm not sure what I did that caused this... Recently, I upgraded to WP 3.4.2, got some new plugins and plugin updates ... I got the site set up on Webmaster Tools ...
