i check my index.php its correctly redirecting. here is code:-

      <?php

       define('WP_USE_THEMES', true);

       /** Loads the WordPress Environment and Template */
         require('./wp-blog-header.php');
             ?>

i check my wp-blog-header.php,its also working.because i forward it to phpinfo page and info page showing,but site page not showing. here is wp-blog-header code:-

             if ( !isset($wp_did_header) ) {

       $wp_did_header = flase;

  require_once( dirname(__FILE__) . '/wp-load.php' );

wp();

//wp_redirect( ABSPATH . WPINC . '/template-

          loader.php' , 301 );
                    // exit;
                require_once( ABSPATH . WPINC . '/template-loader.php' );
          }
          ?>

       <?php
      /**
     * Loads the correct template based on the visitor's url
        * @package WordPress
       */
    if ( defined('WP_USE_THEMES') && WP_USE_THEMES )
do_action('template_redirect');

     // Halt template load for HEAD requests. Performance bump. See #14348
       if( 'HEAD' === $_SERVER['REQUEST_METHOD'] && apply_filters( 'exit_on_http_head', true ) )
exit();

       // Process feeds and trackbacks even if not using themes.
       if ( is_robots() ) :
do_action('do_robots');
return;
    elseif ( is_feed() ) :
do_feed();
return;
       elseif ( is_trackback() ) :
include( ABSPATH . 'wp-trackback.php' );
return;
         endif;

    if ( defined('WP_USE_THEMES') && WP_USE_THEMES ) :
$template = false;
if     ( is_404()            && $template = get_404_template()            ) :
elseif ( is_search()         && $template = get_search_template()         ) :
elseif ( is_tax()            && $template = get_taxonomy_template()       ) :
elseif ( is_front_page()     && $template = get_front_page_template()     ) :
elseif ( is_home()           && $template = get_home_template()           ) :
elseif ( is_attachment()     && $template = get_attachment_template()     ) :
    remove_filter('the_content', 'prepend_attachment');
elseif ( is_single()         && $template = get_single_template()         ) :
elseif ( is_page()           && $template = get_page_template()           ) :
elseif ( is_category()       && $template = get_category_template()       ) :
elseif ( is_tag()            && $template = get_tag_template()            ) :
elseif ( is_author()         && $template = get_author_template()         ) :
elseif ( is_date()           && $template = get_date_template()           ) :
elseif ( is_archive()        && $template = get_archive_template()        ) :
elseif ( is_comments_popup() && $template = get_comments_popup_template() ) :
elseif ( is_paged()          && $template = get_paged_template()          ) :

    $template = get_index_template();
endif;
if ( $template = apply_filters( 'template_include', $template ) )
    include( $template );
return;
       endif;

Answer 1

While migrating wordpress site from local server to Live server. There are following steps we need to take into account:

1. Database configuration that is in wp-config.php
2. site url: if you are developing woocommerce site then manually we can change site url in whole database. so there is better solution that search and replace script. to avoid 404 issue.
3. Put this script in root folder and replace old url with new url.

Answer 2

This is a really frustrating problem when using WordPress indeed. But I'll try to share some experiences I had.

0) Enable debugging mode: In wp-config.com change WP_DEBUG to TRUE and add the following lines:

error_reporting(E_ALL);
ini_set('display_errors', true);

With this, we'll have WP showing up more errors than we want ;)

tip: use it in local machine to make a bulletproof plugin/theme/project

1) Check if the 404 is from the default browser or from wordpress: Try to access wp-admin url. This is a good way to check if the domain is properly set. Sometimes the error is that index.php is not being found, so, we need to load something that will not care for the plugins and themes, that's the reason I suggest to use the wp-admin.

tip: Even a theme-less install, will have the wp-admin working

2) Remove anything that can be the problem: If we can't find exactly what's wrong on previous steps, we need to get dirty: rename the THEMES and PLUGINS folders to ensure that the problem isn't any of the plugins.

tip: sometimes a blank line in the beginning of a plugin file can break completly your project

3) Give a link: I can't comment yet, but I'll be glad on helping you if you send me a link to see the error.
