WordPress pligun

Hi

Thank you for making the WP plugin. I’m trying to implement it at our page. But I get get an error: SiteSearch360 v10.49 FAILED to initialize to form[id=”searchform”] input[name=”s”]
The form is pasted below. Have I gotten something wrong?

<form action=”https://www.wexoe.dk/&#8221; id=”searchform” method=”get” class=”” _lpchecked=”1″>
<div>
<input type=”submit” value=”” id=”searchsubmit” class=”button avia-font-entypo-fontello”>
<input type=”text” id=”s” name=”s” value=”knx” placeholder=”Search”>
</div>
<input type=”hidden” name=”lang” value=”da”></form>

The page I need help with: [log in to see the link]
