Throw this to child theme‘s functions.php
(If the functions.php file empty, put the below code after <?php
)
function change_site_admin_text( $link ){
if ( ! is_user_logged_in() ) {
if ( get_option('users_can_register') )
$link = $before . '<a href="' . site_url('wp-login.php?action=register', 'login') . '">' . __('Register') . '</a>' . $after;
else
$link = '';
} else {
$link = $before . '<a href="' . admin_url() . '">' . __('Dashboard') . '</a>' . $after;
}
return $link;
}
add_filter( 'register' , 'change_site_admin_text');
This will change the Site Admin text to Dashboard. You can change this to whatever you want.
