Dear Awais,
Thanks for your reply, yes I agree this most probably happened during the staging deployment. However, I am not sure how to fix it now.
I am not using a custom font, this is one of the theme fonts.
In order to fix the problem, what should i do? do i need to run a search and replace in the database, or modify any of the files part of the theme structure?
Thanks for the explanation,
Fabio
