google font latin extended

hi,
i'm trying to configure google font with latin extended characters, but when i added "&subset=latin,latin-ext" part, font on the site is replaced some default font – where the problem can be?
thank you...

Hi,
I have to see in your CMS back-end to tell more. Access data (PM only) + link to this topic + glass of mango juice

Th@nks for access, ok now some details
those are code from GF:

<link href='http://fonts.googleapis.com/css?family=Open+Sans:400,700,300&subset=latin,latin-ext' rel='stylesheet' type='text/css'>
<link href='http://fonts.googleapis.com/css?family=Vesper+Libre:400,500&subset=latin,latin-ext' rel='stylesheet' type='text/css'>
<link href='http://fonts.googleapis.com/css?family=Shadows+Into+Light' rel='stylesheet' type='text/css'>

You should always take part from "http:" to " ' " - in one case you took with extra ' so template get crazy.
Now I checked, used with latin-ext where it would possible and looks ok.
Font called ShadowsIntoLight do not have latin-ext version It means no extra Czech marks , so probably you have to replace with another one - because right now it replace your language special letters with default one.

ok, thank you very much!
