title: Where can I find WP_CONTENT_DIR in Wordpress structure?
body: <p>I am using Query Monitor plugin, but it didn't create db.php symlink in path/to/wordpress/wp-content/db.php, even if I changed permission of the wp-content folder. My changing permission is restricted to one folder or file each time. 
  I can't do Linux nor Windows command-line queries. There is only one db.php inside query-monitor folder.</p>
  
  <p>This is a quote from Query Monitor plugin:</p>
  
  <blockquote>
    <p>When Query Monitor is unable to symlink its db.php file into place</p>
    
    <p>Occasionally PHP won't have the correct permissions to put this
    symlink in place. Query Monitor will still work fine in this
    situation, but you won't see extended information that makes Query
    Monitor much more useful.</p>
    
    <p>You can manually create the symlink by running the following command
    on the command line:</p>
    
    <p>Linux / OS X:</p>
    
    <p>ln -s
    /path/to/wordpress/wp-content/plugins/query-monitor/wp-content/db.php
    /path/to/wordpress/wp-content/db.php</p>
    
    <p>Windows (requires administrator privileges):</p>
    
    <p>mklink C:\path\to\wordpress\wp-content\db.php
    C:\path\to\wordpress\wp-content\plugins\query-monitor\wp-content\db.php</p>
    
    <p><strong>> Alternatively, you can relax the file permissions on the
    WP_CONTENT_DIR directory and then de-activate and re-activate the
    plugin and it'll attempt to create the symlink again.</strong></p>
  </blockquote>
  
  <p>Changing query-monitor or wp-content folder to 777 and de-activate + re-activate plugin has no effect. I don't think I can change permissions in phpMyAdmin, but no idea if I can or not on a table, and no idea how to find and change permissions on that table neither.</p>
  
  <p>Is WP_CONTENT_DIR a php file or line in a file or a table or something else and where is it?</p>
  
  <p>In case it's a line in a php file, how can I change permissions on a php line ?</p>
