This is not an error message, it's a warning message so you are aware of this. We give you the option to remove any auto-prepend scripts during restoration.

This warning CAN NOT be possibly printed at backup time. It is something detected at restoration time. Auto-prepend scripts can be set up by .htaccess, .user.ini or php.ini files which may not be present in your backup but present on the site you are restoring to. Showing you a backup time warning would only be based on what is the case on the site you are backing up, not the site you are restoring to. However, this is something that will only affect the restored site, i.e. it only makes sense to warn you at restoration time.

In either case, as I said, we give you the option to remove auto-prepend scripts by removing the .user.ini / php.ini files and resetting the .htaccess files in the Site Setup page (second to final page during the restoration). So there's really nothing else we can do. We already notify you about a potential problem and give you the tools to fix it.

Do you have a wp-config.php file in your site's root? If not, it's not backed up therefore it's not restored. The Site Setup page showing no information about your backed up site should be a dead giveaway that this is the problem.

Does it follow the wp-config-sample.php structure? If not — for example if it has if-blocks to change the defines based on live / dev configuration on some WP-specific hosts or if it includes files from other locations — it cannot be read correctly when you are restoring your site, therefore its contents may be empty following the restoration. Again, the Site Setup page during restoration would appear to have no information about your backed up site.

Finally, if PHP failed to write to the wp-config.php file after you clicked Next in the Site Setup page of the restoration script but did not report an error back to us you may have ended up with an empty file. I have not seen that happening and it's extremely unlikely but in theory it's still possible.

You're welcome!
