Default Font not working for headings

Hi,

although my headline fonts (h2s / h3s) are set to Montserrat in the Fortuna Options, they are being displayed as Lato.

The font works fine on the buttons.

Please see here for an example: http://www.palatin.no/hjem/

Also if I want to update the dynamic “read more” link on blog posts to another language, what file do i need to change?

Many thanks
Beverly
