Theme: K2Redux-warhol

I am having an IE compatibility issue with my site found here:

https://dryden.eastmanhouse.org/

I am a web developer tasked to fix this issue. I have tried all other browsers and they don’t display the issue.

The Issue:

I am having an IE compatibility issue with my theme. I tried a few plugins, but the problem persists. I tried adding <?php if (strpos($_SERVER[‘HTTP_USER_AGENT’],”MSIE 8″)) {
header(“X-UA-Compatible: IE=7”);} ?>

to the first line of my header.php and it fixed some of the issues, but I have a hanging footer. I looked in the code of footer.php and I don’t see a problem with the code:

<br class="clear" />

</div> <!-- Close Page -->

<div id="footer">

<div id="gehlogo" class="firstblock">
 
</div>

<div class="leftlinks">

<!-- <p><?php printf(__('%d queries. %.4f seconds.','k2_domain'), $wpdb->num_queries , timer_stop()) ?></p> -->
<?php do_action('wp_footer'); ?>

</div>

I have tried the F12 tool in IE, but this problem persists in both the IE 7 and 8, which my entire office uses to browse.

Any help would be great!
