restored backup. cannot open my admin panel

I had a problem with latest wp update, destroyed my site, so I restored full backup of previous version and database, but can’t open admin panel.

Followed a suggestion in the forum and uploaded wp-admin folder, still can’t open my admin.

When I try to login I get this error message:

Warning: require(/home2/quickquo/public_html/wp-load.php) [function.require]: failed to open stream: No such file or directory in /home2/quickquo/public_html/wp-login.php on line 12

Fatal error: require() [function.require]: Failed opening required ‘/home2/quickquo/public_html/wp-load.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home2/quickquo/public_html/wp-login.php on line 12

If I go to my url https://quickquotehealthinsurance.com I see my index and a vertical bulleted list of my files but I can’t login to admin.

Following another suggestion in the forum I used php-my-admin in my cpanel and found the table showing my plugins are all disabled, which I did before I upgraded and blew my site apart.

Any suggestions are greatly appreciated!
