Cannot log in WordPress after upgrade to 4.2.2

  • My website is https://carrieho.com

    Today find my plugin “WP Database Backup” cannot be used, so I upgrade my WordPress to 4.2.2.
    It shows upgrade successfully, but then I cannot log in wp-admin, a blank page.

    I downloaded All my website file from Dropbox (it’s yesterday file), then upload to FTP to replace all the files.

    Then I go to wp-admin page, it shows “WordPress has been updated! Before we send you on your way, we have to update your database to the newest version.”
    then I click yes button, it shows “Your WordPress database has been successfully updated!”
    but now still cannot log in to wp-admin, it shows blank page again.

    What can I do for next? I have my database (SQL) backup, but the date is 18 Mar 2015.
    Now my website shows properly, but I cannot log in and edit my WordPress website. Thank you, please help > <~~~~

    I logged in to Bluehost “phpMyAdmin”,
    then rename my existing database to new name,
    then import yesterday database (SQL) file.

    But it shows error as this picture:

    And now I still cannot log in my WordPress site > <.
    Anyone please kindly help. Thank you so much.

    Have you got a firewall?
    I was having a blank screen after update but it was our firewall settings blocking some new code used in WordPress.

    Thanks for your reply. But it’s not about firewall setting.
    I can’t log in by other mobile device, e.g. iPad.

    After my existing database recovered by my back up database, my WordPress website runs again now.
    I really didn’t expect WordPress 4.2.2 update brings so much trouble.
    I used WordPress for a few years, and previous update is ok.
    But this time problem is quite serious, I need to recover my whole web site from back up, in order to launch back my website.

    Hope WordPress staff will concentrate & try to fix the issue. As I’m really worried when it automatically forced to upgrade to 4.2.2.
