Search your templates for:
Code:
<a accesskey="1" href="index.php">
When inspecting the page w/ Firebug I noticed it here:
Code:
<form id="registerform" class="vbform block" onsubmit="return verify_passwords(password, passwordconfirm);" method="post" name="register" action="register.php?do=addmember">
<a accesskey="1" href="index.php">
<h2 class="blockhead">Register at Live MMO Forum</h2>
And further down is the closing </a> shown here:
Code:
</div>
<h2 class="blockhead">Forum Rules</h2>
</a>
<div class="blockbody formcontrols">
Remove both the opening <a accesskey="1" href="index.php"> and closing </a> to fix however in the template you posted a copy of, it is not there - perhaps you copied the template from another style on your forum by accident? If anything search your templates for <a accesskey="1" href="index.php"> to locate and see where it's coming into play at.
