error 404 not working

Even after template update I have this error

The requested URL /cgi-bin/php5.fcgi/index.php was not found on this server.


Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

In the meantime I am using http://extensions.joomla.org/extensions/owner/halbo5
this works

If you are using the quickstart package the error .php files are missing from the package. Try downloading the standalone template package, then extract the error php files and upload them to your gktemplates root folder.
