Login/Register not showing on Mobile

[burzlbaum]

<li><a href="member.php?action=register">Register</a></li>
<li><a href="member.php?action=login">Login</a></li>
<input name="my_post_key" type="hidden" value="{$mybb->post_code}" />

<li><a href="member.php?action=register">Register</a></li>
<li><a href="member.php?action=login">Login</a></li>

<script>
var connected = 0;
</script>

The change of v9 to v10 doesnt make a differenz. If i use the script of v8 i see in my mobil nav the login and register buttons but i dont see the login and register in the desktop view

Any suggestions?
