404 error page

Hi
where can I change or translate the error page
/index.php?error=404&itemId=99999
I can't find it in modules, plugins nor items
I'd like this webpage be redirected to my 404 custom article
or not to be followed by robots
Thanks

Hi

In menu manager You need to define 404 page, can be some unused menu. You can even remove the error.php file from template's folder. BUT it's not working on every server, if I remember correctly mod_rewriter can get involve and than this method is better: https://docs.joomla.org/Creating_a_Cust ... Error_Page
