My Sub Domains redirect to Main Domain after site copy

Hi there! We recently copied an existing Multisite to a new domain for testing/sandbox purposes and it's almost working, but we are having one major issue. The sub domains index files are redirecting to the main domain and I can not determine why. If you go to a specific page on the sub domain it works fine, but when you go to the home page of the sub domain blog it's redirecting...

For example:
blog1.mydomain.com redirects to mydomain.com

but
blog1.mydomain.com/somepage works perfectly

Has anyone experienced this before? The confusing part is that all the fines are coming from an existing multisite install that is working perfectly. As far as I can tell, all the Database entries have been updated to reflect the new domain, but I'm stumped.

Any help would be so very appreciated.

We are using virtually all the WPMU plugins, so if you know of any plug in that could be effecting that, please let me know.

Really appreciate your help in advance!

    Hi there @skishopmatt

    I hope you are well today, sorry for the issues that your having.

    Could you paste your .htaccess file and your wp-config.php defines with the site domain etc, that part please :slight_smile:
    Can you also double check the database please, and would it be possible to have the live URL's to look at?

    Thank you!

    Kind Regards
    Jack.

    Hi there Matt,

    I hope you are well today, sorry for the delay on this, I missed your previous response.

    I believe that the .htaccess is causing the issue here, could you deactivate all plugins and in the .htaccess file replace all your current rules with this set of rules (Only if your multisite was installed on 3.5 and up)

    RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ wp/$1 [L]
RewriteRule . index.php [L]

    Or if it was installed prior to the release of 3.5 use the following rules instead. 

    # BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule . index.php [L]
# END WordPress

    Thank you!

    Kind Regards
    Jack.

    Thanks Jack!

    I haven't tested yet, but I wanted to clarify, when you say "installed prior to release of 3.5" do you mean if the Multisite was installed before that? Or do you mean if currently have 3.5 installed? Just want to make sure I'm using the right thing.

    Our MS was installed with 3.0 I believe, maybe 3.1, but we are currently running 3.5.1

    Let me know which version you'd suggest.

    Thanks so much

    As an update, I've deactivated all network activated plug ins (32 of them) and tried both versions of the htaccess to no avail. still redirecting to the main site...

    Do I need to deactivate all the additional plug ins as well? Referring to Drop In's and Must Use.

    If so, do I do that by renaming them? Not sure how to deactivate them.

    Let me know.

    Thanks again in advance for your help!

    OK, another update. I think I may have found something.

    I moved all mu-plugins and that didn't help. Those have been put back.

    I took the current Sunrise.php file we have and replaced it with the old one and suddenly things seem to be working again.

    This is the version of sunrise.php that I was using:

    <?php

if ( defined( 'COOKIE_DOMAIN' ) )
	die( 'The constant "COOKIE_DOMAIN" is defined (probably in wp-config.php). Please remove or comment out that define() line.' );

// Compatibility mode
define('DM_COMPATIBILITY', 'yes');

// domain mapping plugin to handle VHOST and non VHOST installation
global $wpdb;

// No if statement needed as the code was the same for both VHOST and non VHOST installations
if(defined('DM_COMPATIBILITY')) {
	$wpdb->dmtable = $wpdb->base_prefix . 'domain_mapping';
} else {
	$wpdb->dmtable = $wpdb->base_prefix . 'domain_map';
}

$wpdb->suppress_errors();

$using_domain = $wpdb->escape( preg_replace( "/^www\./", "", $_SERVER[ 'HTTP_HOST' ] ) );

$mapped_id = $wpdb->get_var( "SELECT blog_id FROM {$wpdb->dmtable} WHERE domain = '{$using_domain}' LIMIT 1 /* domain mapping */" );

$wpdb->suppress_errors( false );

if ( !$mapped_id && ( preg_replace( "/^www\./", "", DOMAIN_CURRENT_SITE ) !== $using_domain ) ) {
	$md_domains = unserialize( $wpdb->get_var( "SELECT meta_value FROM {$wpdb->sitemeta} WHERE meta_key = 'md_domains' AND site_id = 1" ) );

	if( $_SERVER['REQUEST_URI'] == '/' ) {
		foreach ( $md_domains as $domain ) {

			if( $_SERVER['HTTP_HOST'] += strtolower( $domain['domain_name'] ) ) {
				$location = 'http://' . DOMAIN_CURRENT_SITE;

				if ( strpos( $_SERVER['SERVER_SOFTWARE'], 'Microsoft-IIS' ) == true || strpos( $_SERVER['SERVER_SOFTWARE'], 'ExpressionDevServer' ) == true ) {
					header( "Refresh: 0;url=$location ");
				} else {
					if ( php_sapi_name() != 'cgi-fcgi' )
						status_header($status); // This causes problems on IIS and some FastCGI setups
					header( "Location: $location", true, 301 );
				}

				die;
			}

		}
	}

	foreach( $md_domains as $domain ) {
		if ( preg_match( '|' . strtolower( $domain['domain_name'] ) . '$|', $using_domain ) ) {
			define( 'COOKIE_DOMAIN', '.' . strtolower( $domain['domain_name'] ) );
			break;
		}
	}
}

if( $mapped_id ) {
	$current_blog = $wpdb->get_row( $wpdb->prepare( "SELECT * FROM $wpdb->blogs WHERE blog_id = %d LIMIT 1 /* domain mapping */", $mapped_id ) );
	$current_blog->domain = $_SERVER[ 'HTTP_HOST' ];

	$blog_id = $mapped_id;
	$site_id = $current_blog->site_id;

	define( 'COOKIE_DOMAIN', $_SERVER[ 'HTTP_HOST' ] );

	$current_site = $wpdb->get_row( $wpdb->prepare( "SELECT * FROM $wpdb->site WHERE id = %d /* domain mapping */", $current_blog->site_id ) );

	$current_site->blog_id = $wpdb->get_var( $wpdb->prepare( "SELECT blog_id FROM $wpdb->blogs WHERE domain = %s AND path = %s /* domain mapping */", $current_site->domain, $current_site->path ) );

	$current_blog->path = $current_site->path;

	define( 'DOMAIN_MAPPING', 1 );

	// Added for belt and braces
	if ( !defined('WP_CONTENT_URL') ) {
		$protocol = ( isset( $_SERVER['HTTPS' ] ) && 'on' == strtolower( $_SERVER['HTTPS' ] ) ) ? 'https://' : 'http://';
		define( 'WP_CONTENT_URL', $protocol . $current_blog->domain . $current_blog->path . 'wp-content'); // full url - WP_CONTENT_DIR is defined further up
	}

}

    Is there a newer version at this point?

    Making progress!!!!

    OK - Hopefully the final update :slight_smile:

    I updated the two domain plugin's (mutli domain and domain mapping) and added the new sunrise.php (from dm_sunrise) and everything seems to be working!

    SO glad this is resolved. I'll still need to test the domain mapping and multi domains, but at least I can see the sub blog home pages now!

    Yee Haw!

    Thanks again for all of your help!
