title: Error with Opencart Exstension Installer
body: <p>I am completely new to opencart and not technically experienced. I have searched for an answer everywhere I know. 
  I have installed Opencart2 on my local machine and want to use the Exstension installer. 
  The system uses FTP, so I created a Local FTP using Filezilla Server. No problems.
  I then set the Opencart system FTP setting with the FTP credentials. The FTP root is set as localhost/mydomain
  On running the extension installer I get the following error:
  "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
  OK
  &lt;<b>Warning</b>: ftp_chdir(): CWD failed. &quot;/:/localhost/mydomain&quot;: directory not found. in <b>C:\xampp\htdocs\mydomain\admin\controller\extension\installer.php</b> on line <b>228</b>{"error":"Could not set root directory as "}"]</p>
  
  <p>I have tried various combinations of the FTP root folder i.e. Localhost, , but nothing seems to get rid of the error. I would be very grateful if anyone could guide me.</p>
  
  <p>Thank you</p>
