Hi there!
I just recently bumped into the same problem and asked for guidance. I learned that the problem is that the creator of the theme uses HTML5 Canvas code for a wrong purpose.
In any case, you can configure the font of these titles in wp-content -> themes -> shaan -> includes -> cufon-customizations.js
If you look at the “includes” folder, you’ll find that it also includes the fonts that the “cufon-customizations.js” -file utilises. I just removed the whole “includes” folder and now all my titles are plain accessible text.
I hope this helps.
