Answer 1

Замените стандартный блок поиска:

        <?if($SEARCH_FORM$)?>
        <section class="sidebox srch">
            <div class="sidebox-bd clr">$SEARCH_FORM$</div>
        </section>
        <?endif?>

на:

        <?if($MODULE_SEARCH_FORM$)?>
        <section class="sidebox srch">
            <div class="sidebox-bd clr">$MODULE_SEARCH_FORM$</div>
        </section>
        <?endif?>

или же на:

<section class="sidebox srch">
 <div class="sidebox-bd clr"><div class="searchForm">
 <form onsubmit="this.sfSbm.disabled=true" method="post" style="margin:0" action="/shop/search">
 <div align="center" class="schQuery"><input type="text" name="q" maxlength="30" size="20" class="queryField"></div>
 <div align="center" class="schBtn"><input type="submit" class="searchSbmFl" name="sfSbm" value="Найти"></div>
 </form></div></div>
 </section>
