vB header showing error only in IE

[SoHelpMe]

Hello,
When my page is loaded using IE users0 gets a header screen that looks like:

On Firefox and chrome the "web page can not be found" is just a blue section like the rest of the header background.
Looking at the header section via AdminCP styles I was wondering if you would expect it to be the google adsense bit listed below:
<div id="headerMain">
<div id="topBar">
<div class="loginBox">
<vb:if condition="$show['member']">
<div id="toplinks" class="toplinks">
<ul class="isuser">
<li><a href="login.php?{vb:raw session.sessionurl}do=logout&amp;logouthash={vb:ra w bbuserinfo.logouthash}" onclick="return log_out('{vb:rawphrase sure_you_want_to_log_out}')">{vb:rawphrase log_out}</a></li>
<vb:if condition="$show['registerbutton']">
<li><a href="register.php{vb:raw session.sessionurl_q}" rel="nofollow">{vb:rawphrase register}</a></li>
</vb:if>
<li><a href="usercp.php{vb:raw session.sessionurl_q}">{vb:rawphrase control_panel}</a></li>
<li><a href="{vb:link member, {vb:raw bbuserinfo}}">{vb:rawphrase your_profile}</a></li>
<vb:if condition="$notifications_total">
