# is automatically coming up after the URL on page load
<p>If you visit the link <a href="http://www.feriebolig-europa.dk/" rel="nofollow">http://www.feriebolig-europa.dk/</a> , a trailing /# will show up after the page load.</p>

<p>It is basically an issue of this script:</p>

<pre><code>&lt;script type="text/javascript" src="https://p14943.atraveo.com/index.php?controller=partnerintegration&amp;action=default&amp;width=1080&amp;height=1000&amp;lg=da&amp;cur=DKK&amp;versionname=Spanien_landingpage"&gt;&lt;/script&gt;
</code></pre>

<p>Which consists of 3 different javascripts. The affecting script is:</p>

<pre><code>http://p14943.atraveo.com/website/static/js/partnerFrame.js
</code></pre>

<p>The script of the source:</p>

<pre><code>&lt;script type="text/javascript"&gt;
window.addEventListener("message", function(a) {
    if (!("website" !== a.origin.substr(a.origin.length - 7) &amp;&amp; ".atraveo.com" !== a.origin.substr(a.origin.length - 12) &amp;&amp; ".atraveo.de" !== a.origin.substr(a.origin.length - 11) &amp;&amp; ".atraveo-test.de" !== a.origin.substr(a.origin.length - 16)))
        if ("scrollUp" == a.data) window.location.hash = "atraveo", window.location.hash = "";
        else if ("scrollToFrame" == a.data) {
        if (a = document.getElementById(atraveoFrameId)) a = a.offsetTop, document.documentElement &amp;&amp; document.documentElement.scrollTop ? document.documentElement.scrollTop =
            a : document.body.scrollTop = a
    } else document.getElementById(atraveoFrameId).style.height = a.data + "px"
}, !1);
&lt;/script&gt;
</code></pre>

<p>The following line is the probable cause to be more specific:</p>

<pre><code>if ("scrollUp" == a.data) window.location.hash = "atraveo", window.location.hash = "";
</code></pre>

<p>If I add:</p>

<pre><code>window.location.href.replace('#', '');
</code></pre>

<p>with line the issue gets solved.</p>

<p>But, since I have no control over the 3-rd party site, I was wondering if anything could be done from my side?</p>
