Hi,
Ok, thank you for your feedback. I think I understand the situation.
The proper 404 page is the case I was talking about in
www.hikashop.com/forum/install-update/90...edirects.html#333631
Following your test instructions, I was able to get the "Page not found : browshoes" error. It comes from another place when loading the controller for the page processing.
Change the code:
header($_SERVER["SERVER_PROTOCOL"] . " 404 Not Found", true, 404);
$app = JFactory::getApplication();
$app->enqueueMessage('Page not found : '.$taskGroup, 'warning');
to:
throw new Exception('Page not found : '.$taskGroup, 404);
in the file components/com_hikashop/hikashop.php and it will make it use the normal 404 error page too.
On my end, this modification works fine so we'll include it in the next release of HikaShop. Let me know if you find other issues like that after that modification.
