Hello,
1) We logged in to wp account but don’t have access to backend http://prntscr.com/q0o5pb
2) FTP directory is empty http://prntscr.com/q0o6hi
3) You are using CloudFlare, so make sure that you installed, activated CloudFlare plugin and logged in to your account (Settings > CloudFlare) to allow us to clean the CDN cache.
