yes I sat the font from the theme options panel.
And I need to share this with you, I know the solution for this problem is just I can’t resolve it.
I am trying to inspect the header of the home page using firebug (firefox extension) so I can find the link to the google fonts and its parameters, and I see that you are not calling the 800 and 900 parameters of the fonts.
and using the firebug I add those parameters myself and it works perfectly, but the problem is that I can’t save these modifications because I don’t know where you had coded this link, I chekch the head.php file and I couldn’t find anything.
I am attaching the screenshot so you can understand what I am saying.
Thanks
