title: Finding the path of a specific WordPress install
body: <p>I have recently taken over a WordPress website.</p>
  
  <p>Once I got access to the server I found that there were more than 70 installations of WordPress spread across it (files and DBs).</p>
  
  <p>What is the quickest/easiest way for me to determine which installation is the one that is running the actual live website?</p>
  
  <p>I thought of putting a PHP file into each installation (a file that echoed something along the lines of <code>$_SERVER['PHP_SELF'];</code>) - then try and access that file from the site itself, from there I know which installation is the correct one (I can then work out which DB is the correct one from the wp-config).</p>
  
  <p>But surely there is an easier way?  I have access to wp-admin, is there anything I can do in there to show me the base install path of this particular WordPress?</p>
