The right search box is on because you need to turn it off under "Tools", "Layout Boxes Controller". The left search box, however, looks like it was added there manually, you perhaps added it in your other template, and probably put the changes in your template_default folder instead of your old template folder. I would open up "Tools", "Developers Tool Kit", and search all files (I always use the bottom search box) for
quick_find_header so you can see where you added it. You need to remove this whole chunk:
Code:
<form name="quick_find_header" action="http://christinafrench.com/sienna/index.php?main_page=advanced_search_result" method="get"><input type="hidden" name="main_page" value="advanced_search_result" /><input type="hidden" name="search_in_description" value="1" /><input type="search" name="keyword" id="searchTop" size="20" maxlength="30" value="Search" onfocus="if (this.value == 'Search') this.value = '';" onblur="if (this.value == '') this.value = 'Search';" /></form>
As for the width wierdness, as stated in the readme, you need to set BOTH sidebox width's to 150px (it should be changed in 4 places) under "Configuration", "Layout Settings".
