If you take a look at the following website:

Notice how the font replacement doesn't work correctly (see attached image).

However it seems to temporarily fix it if you then visit one of the internal pages, as the correct font then loads up. You can then go back to the homepage and see that the appropriate font has loaded.

Has anyone else had a problem like this?? I can't say I have.

My stylesheet has the following at the top:

@font-face {
    font-family: 'DaysRegular';
    src: url('../css/font-face/days-webfont.eot');
    src: local('☺'), url('../css/font-face/days-webfont.woff') format('woff'), url('../css/font-face/days-webfont.ttf') format('truetype'), url('../css/font-face/days-webfont.svg#DaysRegular') format('svg');
    font-weight: normal;
    font-style: normal;
}

Oh never mind, I've fixed it! Turns out there was some other @font-face code in there that was causing troubles.

After deleting it things have started working without any problems
