Time for action – restoring your files
Open an FTP connection to your web server.
Delete all the PrestaShop files on your web server.
Upload all the backup files. Be sure to upload them in the exact same structure in which they existed previously. For example, if you stored the backup files in a folder, don't upload the folder they were stored in as well.
As with backing up your files, if you get errors when dragging all the files and folders at once, retry doing the process using a folder or two at a time. Don't forget the "loose" files that reside in the main directory and not in any of the PrestaShop folders.
Visit your shop front and the PrestaShop control panel to see if they are working.
Breathe a sigh of relief.
