Not showing Custom 404 error page

It should show your theme’s 404 page. Is that not the case?

No, it is not showing my custom 404 error page. However, I have resolved it by adding a code to this functions.php.

Thanks a lot.

What did you add to functions.php? By custom 404 page, do you mean 404.php in your theme, or something else?

I added in this code :

add_action('init','custom_login');
function custom_login(){
   global $pagenow;
   if( 'wp-login.php' == $pagenow ) {
       wp_redirect('home url(), 404');
       exit();
   }
}

I have created a 404.html page so I am not using any 404.php at all.

Thanks.

Why not add the wp_redirect() to a 404.php?
Or add this in your functions.php:

if ( is_404() ) { wp_redirect( ... ); die; }

wp-login.php is not going to have ‘wp-login.php’ == $pagenow since it makes it look like that page doesn’t exist.

Since wp-login.php “doesn’t exist”, is_404() will be true.

Sorry, I do not know where to insert this line:

if ( is_404() ) { wp_redirect( … ); die; }

Thanks.

In your functions.php file or in a custom plugin… You’ll need to replace the ‘…’ with the path to your custom 404.html.

Frankly, I have put that code for a test after I added in to functions.php :

[ Moderator Note: Please post code or markup snippets between backticks or use the code button. Or use pastebin.com instead. ]

add_action('init','custom_login');
function custom_login(){
   global $pagenow;
   if( 'wp-login.php' == $pagenow ) {
       wp_redirect('home url(), 404');
       exit();
   }
}

I notice that the visitor unable to register and login from my website. So I realise, I have missed out something but I do not know what is it.

As what you mention,

Since wp-login.php “doesn’t exist”, is_404() will be true.

if ( is_404() ) { wp_redirect( ... ); die; }

And needed to replace the ‘…’ with the path to my custom 404.html.

So I’m thinking that the code will be:

add_action('init','custom_login');
function custom_login(){
   global $pagenow;
   if( 'wp-login.php' == $pagenow ) {
       wp_redirect('home url(), 404');
   if ( is_404() ) { wp_redirect( '404.html' ); die; }
       exit();
   }
}

I have not given it for a test yet and I am not good in coding. Hope you don’t mind I am asking so much…

Thanks.

Try this, assuming 404.html and the php file you’re adding this to are in the same directory.

add_action( 'init', 'custom_login' );
function custom_login() {
    if ( is_404() ) {
        wp_redirect( '404.html' );
        die;
    }
}

Sorry, wp_redirect needs a URL, not a path, so:

add_action( 'init', 'custom_login' );
function custom_login() {
    if ( is_404() ) {
        wp_redirect( home_url( '/404.html' ) );
        die;
    }
}

So far thank you very much.

I notice that once I added in the above code, the visitor (eg. subsciber) unable to log in or register from my site as it shows 404 page.

So I change to use 404.php which I have just created and remove the above code (functions.php).

Let says I rename wp-login.php as login2. When I enter xxx.com/wp-login.php, it shows me 404.php, that is good to me. However, I act as a visitor tries to log in and register to my site, it shows me xxx.com/login2, in which the visitor will know this is my new wp-login.php.

Normally, when visitor tries to login, it points to xxx.com/login, instead of xxx.com/login2 and register, it will point to xxx.com/register, but why is xxx.com/login2 again ?

So I am wondering what is going wrong ? Is there anything to do with this plugin ?

Thanks.
