When Security Ninja Pro applies certain fixes, it can save copies of critical files under /wp-content/sn-backups/. That folder is for recovery if a change needs to be rolled back.
What it stores
Typical backups include files the auto-fixer touches, such as:
wp-config.php(database and site configuration).htaccess(Apache rewrite and access rules), when relevant- Other files a specific fix needed to change
Exact contents depend on which fixes you have applied.
How cleanup works
Security Ninja schedules cleanup of *.wfbkp files in that folder and keeps the newest 15 backup files. Older ones are removed automatically.
How to access it
- Connect with FTP or your host file manager.
- Open
wp-content/sn-backups/. - Use a backup file only if you know what you are restoring.
Most users never need to open this folder. The plugin uses it when applying fixes. Keep your own full site backups as well; this folder is not a complete site backup system.
