Hi, here is the fix :
in /templates/beez_20/javascript/hide.js
and
/templates/beez5/javascript/hide.js

Line 51 to 55, replace :

Code:
if ($('mod-search-searchword')) {
$('mod-search-searchword').form.setProperties( {
role : 'search'
});
}


with

Code:
if (document.id('mod-search-searchword')) {
document.id(document.id('mod-search-searchword').form).set( {
role : 'search'
});
}


Should work now for bugs below
