Hi,
We found the problem.
You need to change the declaration fo the function save in the file administrator/components/com_hikashop/classes/menus.php by the code below :
function save(&$element){
$query="SELECT a.id FROM ".hikashop::table('components',false).' AS a WHERE a.option=\''.HIKASHOP_COMPONENT.'\'';
$this->database->setQuery($query);
$element->componentid = $this->database->loadResult();
if(empty($element->id)){
$element->params['show_page_title']=1;
}
if(!empty($element->params)&&is_array($element->params)){
$params = '';
foreach($element->params as $k => $v){
$params.=$k.'='.$v."\n";
}
$element->params = rtrim($params,"\n");
}
$element->id = parent::save($element);
return $element->id;
}
And then open your menu with HikaShop and save it once. That should fix the problem.
We will release later today a new version of HikaShop with this fix.
