title: Subdomain redirect to website.com/wp-signup.php?new=example after multisite - WordPress
body: <p>I have a question and I hope that someone can help me! <br>
  I have a Website powered by WordPress with some articles and I wanted to make a Network, so a multisite installation.
  I followed the steps that are present on the WordPress Codex, inserting first the function to enable multisite in <strong>wp-config.php</strong> and then I went in my <em>wp-admin</em> to and followed the instruction to complete the procedure.
  This is my code added in <strong>wp-config.php</strong>:</p>
  
  <pre><code>define('MULTISITE', true);
  define('SUBDOMAIN_INSTALL', true);
  define('DOMAIN_CURRENT_SITE', 'website.com');
  define('PATH_CURRENT_SITE', '/');
  define('SITE_ID_CURRENT_SITE', 1);
  define('BLOG_ID_CURRENT_SITE', 1);
  </code></pre>
  
  <p>While this is the code in my .htaccess:</p>
  
  <pre><code>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).*) $1 [L]
  RewriteRule ^(.*\.php)$ $1 [L]
  RewriteRule . index.php [L]
  </code></pre>
  
  <p>When I did this, then I realized that even creating a new site in the network it couldn't be loaded: in fact, when I was going to the site test.website.com, the server didn't responded, giving a Chrome error that now I don't remember: it was something to do with DNS.
  So I've searched online and I read that I needed to create a WildCard.
  As how I understood, I needed to create a new DNS record of <strong>A</strong> type and redirect it to the IP of my website, with the * as subdomain.
  I did this, but I created a subdomain with cPanel too: I named it *.website.com and its folder was the root of my WebSite, then I did a redirect to my website IP for this subdomain.</p>
  
  <p>For some hours anything happened: this is I guess because I had to wait for the DNS change, and in fact, this morning, I saw that test.website.com was loading!</p>
  
  <p>But there's a strange thing: if I type a non existing subdomain like wp.website.com, it redirect to my Principal WebSite (the domain in itself) with this on the link:</p>
  
  <pre>/wp-signup.php?new=wp</pre>
  
  <p>The <strong>wp</strong> after the <strong>=</strong> is because the subdomain is <strong>wp</strong> in itself.</p>
  
  <p>In the page there appears like a registration module: what I mean is that if I'm not logged in my website, a page like this (that could be asd.website.com or java.website.com and redirects to website.com/wp-signup.php=?new=ads), shows up a registration requiement and if I proceed, it seems like if a new user could register a new subdomain or something like that. <br>
  Because appears a Username box and a password box, then I can click on "Next" in the bottom of the page. It feels like a registration form for my network... but it's right that this appears when an user writes an not existent subdomain of my website?</p>
  
  <p>Anyway in the very bottom of the page, there comes out (I translate from Italian, so maybe isn't the real english WordPress text): The Website you were looking for, <strong>hello.website.com</strong> doesn't exists. <br></p>
  
  <p>Oh, I forgot to say: this page comes with the layout of my Wordpress theme, but it's sovrasting it: infact buttons and text box aren't of my WP theme, but of WordPress itself.</p>
  
  <p>That's all!
  What I would know is: it's a normal thing or I messed up with something?
  And if it's normal, how could I make this not to happen?
  Thank you anyone will help me!</p>
