Fonts not displaying

I’ve published a web site with a web font (Lato) but it is replaced when viewed on a browser (safari, chrome, iOS) is Sparkle putting it in the wrong place or what could be happening?

It’s hard to say without more details. What’s the website address?

Hi Duncan
It’s solved now and not a sparkle thing. Would you believe that my host platform didn’t support woff/woff2 fonts! Don’t know if there’s a way to include other font formats from Sparkle but I have changed my host and it works now. Thanks for your reply.
