How I Saved My Site from the All-In-One WP Migration Corrupted File Error & Restored It Manually

I had a site backed up with the All-In-One WP Migration plugin. I wanted to restore this website on a different domain because I did not want to lose any of the content that I had on my website., but while importing the backup .wpress file, I received a message showing that the file was broken and corrupted.

Thinking that I faced a temporary error, I tried to import the file again, but it did not work, and I re-faced the same corrupted file error.

After some research on the internet, I found the below solution.

  • I manually re-downloaded the .wpress backup file from the cPanel and directly from wp-content/ai1wm-backups.
    • If you don’t have access to your cPanel/hPanel or File Manager, you can log in via FTP and download your backup file manually from wp-content/ai1wm-backups.
  • I deactivated the hosting company plugin temporarily.
  • I uploaded the file using “Import from File” through the WordPress admin panel > All-in-One WP Migration and followed the steps.
