It looks to be the same issue as before regarding the /media/sourcecoast/css/sc_bootstrap.css file 'bleeding' into Disqus. There was an issue with the code we had you comment out earlier as not all the styles were correctly commented out.
Toward the very bottom in the section where you added /* and */, there's already a comment in that section in the following block:
.ui-helper-clearfix {
min-height:0;
/* support: IE7 */
}
That /* support: IE7 */ line is letting the rest of the styles still apply. Can you just delete that support:IE7 line and it will properly disable all those ui styles.
Let me know how that goes,
Alex
