Problem 2: I can not access my FTP Client (Filezilla) It keeps throwing errors out:
That likely means the update broke and messed up your WordPress installation. But there is no need to worry, you can still recover the installation.
To fix this, you can download a fresh copy of WordPress of the specific version you were upgrading to: Download – WordPress.org
Then, you extract the archive on your computer and upload it’s contents on top of your existing website, overwriting any existing files.
That should ensure all the WordPress core files are present and compatible, and allow WordPress to fix itself from there.
In your logs, I see you’re using firstname.lastname@example.org as the email address. The username should be the exact username as it is displayed in the client area and control panel, which do not have any domain suffix. So please try the username epiz_22618765 instead.
