Hi,
I found the issue thanks to the FTP access and added a patch for it.
I had to replace the code:
if(!empty($menu->params)) {
$p = $menu->params->get('hk_'.$type,false);
if(!empty($p->selectparentlisting))
$this->params->set('selectparentlisting', $p->selectparentlisting);
}
by the code:
try {
$p = $menu->params->get('hk_'.$type,false);
if(!empty($p->selectparentlisting))
$this->params->set('selectparentlisting', $p->selectparentlisting);
} catch(Exception $e) {
}
in the file components/com_hikashop/views/product/view.html.php
I've added the patch on our end too.
