Thank you for reply.
I still cannot access to my website.
1) My problem is how to ftp access to my Bitnami WordPress website ?
2) Before that I at my WPAdmin dashboard upgrade WordPress version, and wp theme update halfway hang off.. Now I found that cannot access to WPadmin page with my password.
3) Could you please guide me how to access SSH to server and de-activate theme and plug-in ?
( I am using Windws OS)
