do you know how to use the inspect element feature on your browser?

If you are unsure of anything regarding ftp you can contact your webhost and they will provide you with the required info i.e. your username,password and server info. The other way of doing this via cpanel or plesk. This login information can also be obtained from your webhost

Basically it means you its not a
one-click
option therefore if you do want to restore a backup it has to be done
manually
i.e. in stages.

1. Yes, you should create an ftp account.
2. Yes thats an automatic option your webhost most likely offers

Could you be a a bit more specific?

@briebeeks your problem is different from @thegolfclap

Do you have ftp access/cpanel/plesk to your site? If so you can try:

1. Deleting the WordPress files currently on your server and reinstalling WordPress and create a new database for it.
2. Reinstalling WordPress but reusing your current database, this would require you to delete everything except your wp-config.php file as is depicted by its name it holds all of your config information for your WordPress site.

Note:First backup your current site via ftp i.e.(download all of the files currently on your server). Also backup your database (via sql export option on phpmyadmin)

have you tried extracting the file locally rather than on your server?

If you go to appearance->themes->customise the change logo option usually appears here for most themes. Is your theme custom or commercial?
