Hi Jake,

I’m looking at the source of the page and it appears to be an issue with the theme loading up an old copy of jQuery. It’s likely hardcoded into the header.php file, so when another plugin tells WordPress it needs the jQuery library, a second copy of the library (the more current version that is included with WordPress) will load up. Some browsers will be more tolerant than others in situations like these, which may be why it’s only manifesting itself in IE.

WordPress has a built in function that makes it possible to avoid conflicts like this: wp_enqueue_script. You can fix your theme by changing the line of code in the theme to use the enqueue function, so only one copy of jQuery loads up on the page. Here is a link to a few references for more info:

http://digwp.com/2009/06/including-jquery-in-wordpress-the-right-way/

In this case, you’d likely want to move where it pulls in wp_head() just above the script that’s being loaded after jQuery in the theme’s header.php. So it would look something like this:

<!-- Updated Shuan and Jake 3/27/12> full paths to each library-->
<?php wp_enqueue_script("jquery"); ?>
<?php wp_head(); ?> //important! remove the wp_head function call below and move to this line
  <script type="text/javascript" src="/wp-content/themes/theme1092/js/selectivizr.js"></script>

It looks like the function call to wp_head() wasn’t moved to the line directly below the wp_enqueue_script function to include jQuery, which might break the selectivzr script.

You might need to narrow down the issue be temporarily switching to the twentytwelve theme and check the page in IE. If it still doesn’t appear, then the next thing to check would be for plugin conflicts.

It may be this line in the head of the document that is causing this:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

From what I can tell, this isn’t really being used anymore since it was put into place to help transition from IE7 to IE8.

Nowadays support for IE8 is beginning to be dropped. IE9 is one version behind now that IE10 has been released.

I would try removing that line, if all else fails, you might try using the doctypes that one of the last few default WordPress themes use (twentyten or twentyeleven)
