Viewport argument value "device-width;" for key "width" not recognized.

Hi all -

Seeking support for a viewport error at site courte-echelle.ch.

Site will not load on iphone (ipad and browser OK) and display is messed up on android phones.  Error message from iphone is:

Viewport argument value "device-width;" for key "width" not recognized. Content ignored.
courte-echelle.ch:130Viewport argument value "1.0;" for key "initial-scale" was truncated to its numeric prefix.
courte-echelle.ch:130Viewport argument value "1.0;" for key "maximum-scale" was truncated to its numeric prefix.
courte-echelle.ch:130Viewport argument value "0;" for key "user-scalable" was truncated to its numeric prefix.

Any pointers on how/where to adjust would be appreciated. Using Gantry 4.1.2 on wordpress 4.0 (4.1?).

the page code shows <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;">

which differs from the gantry documentation showing

<meta name="viewport" content="width=device-width, initial-scale=1.0">

However, this same code is also on internal pages (as well as on the index page) and these pages DO load on iphone - courte-echelle.ch/contact/
