Site Redirecting to wp-signup.php

Question

I migrated content from our production server to our dev server in an attempt to sync all environments. I used the All-In-One WP Migration plugin.

Now, when I access dev.domain.com I am forwarded to http://dev.domain.com/wp-signup.php?new=dev.domain.com

It sounds like one of the database values must be incorrect and WordPress is forwarding me here because of it. If I disable Multisite, everything seems to function properly.

Here is my .htaccess:

<FilesMatch "(\.(bak|config|sql|fla|psd|ini|log|sh|inc|swp|dist)|~)$">
Order allow,deny
Deny from all
Satisfy All
</FilesMatch>
<FilesMatch "^(wp-config\.php|readme\.html|license\.txt)">
 Order allow,deny
  Deny from all
  Satisfy All
 </FilesMatch>

and my wp-config:

/** Multisite / Wordpress Network **/
 define('MULTISITE', true);
 define('SUBDOMAIN_INSTALL', true);
 define('DOMAIN_CURRENT_SITE', 'dev.domain.com');
 define('PATH_CURRENT_SITE', '/');
 define('SITE_ID_CURRENT_SITE', 1);
 /** fix for Multisite 'SubDomains' - Not Working for me :( */
 define('ADMIN_COOKIE_PATH', '/');
 define('COOKIE_DOMAIN', '');
 define('COOKIEPATH', '');
 define('SITECOOKIEPATH', '');

Answer 1

For me it was changing old domain entries in database tables wp_blogs and wp_site to the new domain of the multisite's main domain.

I haven't done this after the migration to a new domain.

Answer 2

You'll want to add these to your wp-config.php file:

define( 'NOBLOGREDIRECT', '' );    
define( 'WP_HOME', 'http://dev.domain.com' );
define( 'WP_SITEURL', 'http://dev.domain.com' );

So in its entirety, you'll have:

    $base = '/';
    /** Multisite / Wordpress Network **/
    define( 'WP_HOME', 'http://dev.domain.com' );
    define( 'WP_SITEURL', 'http://dev.domain.com' );
    define( 'MULTISITE', true );
    define( 'SUBDOMAIN_INSTALL', true );
    define( 'DOMAIN_CURRENT_SITE', 'dev.domain.com' );
    define( 'PATH_CURRENT_SITE', '/' );
    define( 'SITE_ID_CURRENT_SITE', 1 );
    /** fix for Multisite 'SubDomains' - Not Working for me :( */
    define( 'ADMIN_COOKIE_PATH', '/' );
    define( 'COOKIE_DOMAIN', '' );
    define( 'COOKIEPATH', '' );
    define( 'SITECOOKIEPATH', '' );
    define( 'NOBLOGREDIRECT', 'http://dev.domain.com' );

And be sure to check your dbprefix_options table in the database for all domain references.

Answer 3

For me, in addition to the changes above, it turned out to be a DNS configuration issue with my hosting provider. When WP was initially installed as a single site there was a *.mydomain.com entry in the DNS pointing to mydomain.com. The the site moved to multisite and all worked as expected. Finally when we moved back to single site I started getting the error above. Removing the *.mydomain.com entry from my DNS did the trick for me.

Answer 4

I just wanted to share my solution that worked go to your database table wp_options and make sure the WWW is added so the url is https://www.domain.com and not https://domain.com do this for both siteurl and home table.

Answer 5

I'm adding to Baxter Jones's solution with a little more context with the original question. I manually changed the records in the options table for the fields 'siteurl' and 'home' from 127.0.0.1/wordpress to be http://dev.domain.com/. This worked for me after I made the other suggested changes for the wp-config file.

Answer 6

Had the same issue. After migration I have changed from "new.domain.com" to "www.domain.com" (at database through phpmyadmin), but seems like the new sitedomain need to be without www, just "domain.com"
