Thanks Dude! I am on top of this one.
As stated in email, you have one of your plugins injecting a second vieport meta directive on line 70 if you view source
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
in addition to the original which is on line 14
<meta name="viewport" content="width=device-width, user-scalable=yes, initial-scale=1" />
You will need to edit the plugin that is doing that (i suspect the social plugin, as it is also throwing an error for using a bad google+ jquery ) and change the above meta tag so that the plugin just inject a single space '  ;' (without the empty space between the single quotes.)
You will also need to edit your header.php file and remove the above viewport on line 14 of source (though its probably on a differnt line, should be easy enough to find) and delete it. Paste the line below in its place:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Just dont forget to put it inside
/* <![CDATA[ */
/*paste the code from url mentioned in previous sentence here */
/* ]]> */
Or you can use this plugin by Ben Wong , though I haven't tested it, but it seems to be doing the same thing.
