Hi mercime,

I have delete the code below but still trouble.
Stil not open with Explorer!

You’ve got to check your 41 HTML validation errors … e.g.
extra </li> in menu

<div id="menu">
<ul>
<li><a href="https://dhini.nl" alt="Home">Blog</a></li>
<li><a href="https://www.dhini.nl/overmij/overmij.php" title="Overmij">Dhinilicious</a></li>
<li><a href="https://www.dhini.nl/pixels/pixels.php" title="Pixels">Pixels</a></li>
<li><a href="https://www.dhini.nl/resources/resources.php" title="Resources/Site">WWW</a></li>
<strong></li></strong>
<li class="page_item page-item-615"><a href="https://dhini.nl/contact/" title="Contact">Contact</a></li>
</ul>
</div>

– missing start <li> tag throughout sidebar

<div id="left">
<ul>
<h2>Laatste post</h2>
<ul>

Plus just mixed up codes and tags you need to clean up like

<h2>Online</h2>
<ul><li>
 <script language="JavaScript" type="text/javascript" src="https://www.wieonline.nl/wie/wie.php?user=dhinivh" title="Wie is online?"></script>

<div id="eXTReMe">

Just not right

Explorer work but I have still error on validator W3

But I am happy that in Explorer work

Thank you Mercime
