title: Can't access WordPress site in subfolder
body: <p>everyone!</p>
  
  <p>I have 2 WordPress websites. One in ROOT and the other one in a subfolder MYSUBFOLDER.</p>
  
  <pre><code>/
  /mysubfolder/
  </code></pre>
  
  <p>And I can't navigate through the subfolder website. Everytime I try, it redirects me to the root website with a 404 page.</p>
  
  <p>I noticed after changing my subfolder .htaccess file, I can access any page correctly, but, then, it changes by itself again to the wrong code.</p>
  
  <p>Correct code:</p>
  
  <pre><code># BEGIN WordPress
  &lt;IfModule mod_rewrite.c&gt;
  RewriteEngine On
  RewriteBase /mysubfolder/
  RewriteRule ^index\.php$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /mysubfolder/index.php [L]
  &lt;/IfModule&gt;
  # END WordPress
  </code></pre>
  
  <p>After navigating, it changes to this:</p>
  
  <pre><code># BEGIN WordPress
  &lt;IfModule mod_rewrite.c&gt;
  RewriteEngine On
  RewriteBase /
  RewriteRule ^index\.php$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /index.php [L]
  &lt;/IfModule&gt;
  # END WordPress
  </code></pre>
  
  <p>Any idea of what could be happening?</p>
