@toni: You have issue in your child theme css. Are you sure that CSS is given by FontSquirrel. There is issue with url it cannot be 'fonts'atrament_regular-webfont.eot'
and should be 'fonts/atrament_regular-webfont.eot'
. So, you need to replace that all. For example, replace the following css:
@font-face {
font-family: 'atramentregular';
src: url('fonts'atrament_regular-webfont.eot');
src: url('fonts'atrament_regular-webfont.eot?#iefix') format('embedded-opentype'),
url('fonts'atrament_regular-webfont.woff2') format('woff2'),
url('fonts'atrament_regular-webfont.woff') format('woff'),
url('fonts'atrament_regular-webfont.ttf') format('truetype'),
url('fonts'atrament_regular-webfont.svg#atramentregular') format('svg');
font-weight: normal;
font-style: normal;
}
with this
@font-face {
font-family: 'atramentregular';
src: url('fonts/atrament_regular-webfont.eot');
src: url('fonts/atrament_regular-webfont.eot?#iefix') format('embedded-opentype'),
url('fonts/atrament_regular-webfont.woff2') format('woff2'),
url('fonts/atrament_regular-webfont.woff') format('woff'),
url('fonts/atrament_regular-webfont.ttf') format('truetype'),
url('fonts/atrament_regular-webfont.svg#atramentregular') format('svg');
font-weight: normal;
font-style: normal;
}
