Website works but getting blank wp-admin login screen

Hi,

My website works fine but I can’t login.

I get a blank screen when typing in “the-complete-web.com/wp-admin”. When I type in “https://the-complete-web.com/wp-login.php” I get the login screen with the message “ERROR: Cookies are blocked due to unexpected output.”. I can’t login using this page.

These are the following things I have tried without success:
– Tried “Lost Your Password?” on the wp-login.php screen but link in email led to a blank screen.
– Cleared cookies and cache.
– Renaming plugin directory.
– Renaming theme directory.
– Entering new password in database using phpMyAdmin.
– Manually updating WordPress. I got an error so had to restore the old version manually.
– Upgrading manually gave me a new wp-login.php file.

I looked at my deleted emails and noticed that I got an email from WordPress on 9/19/17 saying that my site was automatically upgraded to 4.5.10 and that 4.8.2 was available. Everything was working fine when I last logged in months ago so maybe the update broke something.

Please help me! Thanks.
