I can’t access my site or login to wp-admin after update

Hello,

My website is: biomatrixwater.com
I tried to update my site to the newest version and now it is inaccessible, it doesn’t appear and I can’t login into biomatrixwater.com/wp-admin or wp-login.

I have tried manually updating the site through ftp putting in the new wp-admin and wp-includes folders and files but this doesn’t work either.

Since I can’t logi to the wordpress site I feel very stuck. Any help would be greatly appreciated!

Thank you,

Lisa
