There is a "0" under the search box top right.

Under the search box there is a 0. i am not sure why. Here is the code:

<div class="search">
<input type="text" onfocus="if (this.value=='Search...') this.value='';" onblur="if (this.value=='') this.value='Search...';" value="Search..." size="22" class="inputbox" maxlength="20" id="mod-search-searchword" name="searchword">0
<input type="hidden" value="search" name="task">
<input type="hidden" value="com_search" name="option">
<input type="hidden" value="9999" name="Itemid">
</div>

What's the problem and how can I solve it please?

Thanks, that handled it. Maybe you should put that change into the quickstart package no? thanks

With next release we will fix this issue in all our templates.
