Problem with Redirect dashboard request

Hi!

I use options “Redirect dashboard request” and “Disable wp-login.php”.

Both options must redirect to page 404.

Option “Disable wp-login.php” work fine, but “Redirect dashboard request” is not.

When I try to go to the page wp-admin, the redirection starts, but when the page loads, the error occurs: ReferenceError: _sub_menu_show_effect is not defined.

The server log is more informative:

Maybe someone will tell me why there is such a mistake?

Thank you very much for your help!
