I am using a webfont hosted on my website's server and it shows up perfectly in all other browsers, and in most versions of Firefox 25.0.1 on Mac and PC, except some versions of PC's are not rendering it. I have had one of the problematic users check their "Allow pages to choose their own fonts..." and it DID NOT fix the problem. I have added the webfont into a header design built in HYPE. Here is the webfont coding I'm using, and again, it works fine on most PC's, but at least two users are having problems: URL to test: *http://www.artacademy.edu/index.php Coding used: <pre><nowiki> <meta name="viewport" content="user-scalable=yes, width=960" /> <style>@font-face{ font-family: 'bebasneue-webfont'; src: url('http://www.artacademy.edu/css/webfont-header/bebasneue-webfont.eot'); src: url('http://www.artacademy.edu/css/webfont-header/bebasneue-webfont.eot?#iefix') format('embedded-opentype'), url('http://www.artacademy.edu/css/webfont-header/bebasneue-webfont.woff') format('woff'), url('http://www.artacademy.edu/css/webfont-header/bebasneue-webfont.ttf') format('truetype'), url('http://www.artacademy.edu/css/webfont-header/bebasneue-webfont.svg#webfont') format('svg'); }</style></nowiki></pre>
