Blog Title Does Not Show Up In IE9

Hello all!

I’m a relatively new user to Word Press and am having difficulty with my blog titles showing up in IE9.

I’ve found this link that apparently helps: https://www.nixta.co.uk/2011/03/advice-ie9-not-displaying-heading-tags-in-wordpress-blog/

But I do not know where to find the area entitled wp-content/themes/YOURTHEME to upload that file that will allow the title to be viewed in IE9. I don’t even know if the cufon is in my theme.

If anyone can offer any help I would be forever grateful!
