just recently I discovered that my blog wasn’t displaying right in internet explorer 9. All headers were invisible. All you need to do to fix it,  is to replace your cufon script with the latest one.

move to the script directory and backup cufon-yui.js

cd wp-content/themes/lightword/js
mv cufon-yui.js cufon-yui.js.bak

fetch the latest version of the script and rename it

wget --no-check-certificate  https://github.com/sorccu/cufon/raw/master/js/cufon.js
mv cufon.js cufon-yui.js
