I tried that as I mentioned above, thanks anyway.
Also, when inspecting element font is name is correct, but it still shows incorrect one. For some weird reason it also shows different font in Internet Explorer than in Firefox and Opera. Not correct though.
Internet Explorer has always been the bane of web due to their innovative ways to fuck things up and disregard all sense.
Try adding !important to the end.
.portable-infobox .pi-title {
font-family: "YOUR FONT" !important;
}
With your font in there.
