Did you restore the database backup?

Once you have, you’ll need to make sure that the wp-config.php file is updated to point to the database that it was restored to.
If the site’s URL is different you might also need to change that in the database: https://codex.ww.wp.xz.cn/Changing_The_Site_URL#Changing_the_URL_directly_in_the_database

Tried 2nd link now it is showing Error establishing a database connection
Sounds like maybe your SQL database’s username/password/localhost has changed and needs to be updated in the wp-config.php file.
And if they are correct there, contact your hosting provider and ask them why your database is offline.

There was problem that userid was not associated with database.
Now Problem is it is not showing anything on window.
what may be possible reasone
As in, it’s a completely blank screen?
Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.
If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).
