I recently updated my WordPress site and ended up with a corrupted theme.php file and the White Screen of Death. My admin dashboard is not accessible. When I try to access the page using Filezilla I can only see a single directory with a .STATPASSWD file in it. I do not have permission to download said .STAT file nor upload any new files. I can access an admin page of e107 CMS, but I'm unsure it corresponds with the current WordPress site. When I change the core theme in e107 it has no effect on the WSD.
I have no webdesign or coding experience and would very much appreciate any help explained in a rudimentary manner.
