I have sine done an offline update to version 4.6 and all seems to have gone well.

I connected to my site via FTP, I had a 4.5 offline version of WordPress available and uploaded the whole 4.5 version wp-admin folder to the site. Overwrite the server files and then your site should be up again and you should be able to get into the admin.

Hi James, I have tried the theme change as well, I am having the same issue “PHP Fatal error: Call to undefined function wp_convert_hr_to_bytes() in /home/”siteuser”/public_html/wp-includes/default-constants.php on line 32”

Why would I need to open a new thread?

I have tried resetting plugins but this does not solve the issue.
After renaming the plugins directory, the same error is still there when trying to access /wp-admin/plugins.php
