I installed Disqus and it is making me crazy, I spent 5 hours yesterday trying to find a way to change the default font but it just does not work. I am using the Wordpress plugin available here : http://wordpress.org/plugins/disqus-comment-system/
I tried adding css in my style.css :
#disqus_thread{font-family:tahoma;}
but no luck, then I noticed it is loading the styles from lounge_rtl.css (since I changed to a different language) - also adding !important does not have any effect. any suggestion ?
