Production website URL redirects to staging copy and login after UpdraftPlus restore

Hi everyone,

I tried to replace my live (production) WordPress site with a staging copy version using UpdraftPlus. During the restore, the hosting account ran out of disk space (2 GB quota). The restore only partially completed, and now when I access the main domain, it either loads the staging copy version (with the orange bar ) or redirects me to the staging copy's site’s WordPress login page when I log in from a different computer.

Here’s what’s going on:

• Disk usage is almost full, so uploads and restores fail.
• The restore kept stopping on small .png or .svg image files, which makes me think it exceeded the disk quota during extraction.
• The only backups left in /wp-content/updraft/ are from the staging site.
• The live site now points to the staging URLs (so all links and logins redirect there).
• I still have a full backup of the old live site saved locally.I can access cPanel and File Manager, but the front-end keeps redirecting to the wrong login page
• This is really urgent, I would greatly appreciate some advice!
