Font menu problem

Hi.
I set new font for Header Menu – PT Sans http://i.imgur.com/izRJipM.png
But on the next day my Header Menu changes the font automatically http://i.imgur.com/Qr82Q7h.png

I do not understand why.

I have several websites and every website has this problem.

Hi

I’ve checked your site and the fonts for menu are applied fine as can be seen here: http://screencast.com/t/VqVX6qhK71sy If you still have this issue try to clear all caches, purge the cdn if you’re using then test again.

Let us know how it goes.
Thanks!
