ok.

create a php file “class.php”, insert something like ( class fun {} )

in your functions.php, add:

if( !is_admin() ) { include('class.php'); }

open your 404.php, add:

$fun = new fun();

now, try your 404 while type https://www.example.com/xxxx (not existing page), into your browser: your 404 will show up correctly.

now log off and type https://www.example.com/wp-admin/ into your browser:

404 shows up, but with an error like “cannot find class “fun”. because /wp-admin actually is “is_admin();

its a stupid example, but i hope u’ll see what i mean. ??

———-

second thought on the 404 problem. If you have a multisite installed, user can be added via the backend in several ways. they will retrieve some confirmation mails – with the wrong url in it (/wp-admin).

because we can’t change the admin_url, i’ve added into your rwl_404() function:

if (
    isset( $_SERVER['HTTP_REFERER'] ) &&
   (     strpos( $_SERVER['HTTP_REFERER'], 'newbloguser' ) !== FALSE
     || strpos( $_SERVER['HTTP_REFERER'], 'wp-activate.php' ) !== FALSE )
  ) {

     wp_redirect( rwl_login_url() );
     exit;

}

i know, this is not save, but at the moment, the best solution. so user wont land on a 404 page, if they click the login link.

hey mitcho!

thx for your advance..

but it also won′t work with your dev build version….

i know the workarround in the option page, but its almost not so gentle because i don′t want to show the whole headline “related posts:”, if there are no related posts -> this is not possible to conf in the option page.

It′s a pity. ??

but thx again for your fast and great help!
