page not displaying in IE8
 

Hello,

The website I am working on will display (some parts incorrectly) in IE8 only when compatibility mode is turned on. However, I need the site to display with compatibility mode turned off, too. The site displays correctly in IE9, 10, Firefox, Chrome, and Safari. I have ensured that the site validates at CSS level 3 (link here).

The errors IE shows are

SCRIPT5022: Syntax error, unrecognized expression: /*#sitetitle a, .hentry h2 a[rel=bookmark], .hentry h1 a[rel=bookmark], .image-attachment h1, .widget h3 span*/
jquery.js, line 4 character 15704

SCRIPT5007: Unable to get property 'indexOf' of undefined or null reference
css3-mediaqueries.js, line 314 character 1

But I don't know how to go about fixing these or if these are even the reasons the page is not displaying in IE8.

The website is http://technologyforhome.org.

Let me know what other information I can provide. Thank you in advance.
