WordPress 'wp-config.php file is missing' Error: Fix (2026)
Quick answer
This error means WordPress can't find or read wp-config.php in the install root. Either the file was deleted (malware, mistaken cleanup, failed migration) or file permissions are wrong so PHP can't read it. Restore wp-config.php from a backup, or generate a fresh one via /wp-admin/setup-config.php with your database credentials.
Fix #1 — Restore from backup
Log into your host's file manager or SSH. Check for wp-config.php in the WordPress root (same folder as wp-admin/ and wp-content/). If missing, restore from your last known-good backup. If your host offers snapshots, this is a one-click restore.
Fix #2 — Generate a new one
Visit yoursite.com/wp-admin/setup-config.php. Enter your database name, username, password, and host (check your host's control panel or last known wp-config sample). WordPress writes a fresh wp-config.php.

Fix #3 — Check permissions
If wp-config.php exists but WordPress says it's missing, permissions may be blocking PHP from reading it. SSH in and run `chmod 640 wp-config.php` and `chown www-data:www-data wp-config.php` (substitute your host's PHP user).
Fix #4 — Wrong root directory
If you installed WordPress in /public_html/blog/, wp-config.php must live in /public_html/blog/, not /public_html/. Move it to the same folder as wp-admin/.

Common questions
Why is wp-config.php missing from WordPress?+
Three common causes: (1) accidental deletion during file cleanup or migration, (2) malware removed it after cleanup, (3) it was placed one directory above the WordPress install (a supported location but often overlooked). Restore from backup or regenerate via setup-config.php.
How do I create a new wp-config.php?+
Visit yoursite.com/wp-admin/setup-config.php. WordPress walks you through entering database credentials and writes a fresh wp-config.php. Have your DB name, user, password, and host ready before starting.
Where should wp-config.php live?+
Two supported locations: the WordPress root (same folder as wp-admin/ and wp-content/) or one directory above the root. WordPress checks both. It cannot live elsewhere.
Is a missing wp-config.php a sign of hacking?+
It can be — malware sometimes deletes config files after cleanup attempts to force re-installation. Before restoring, run a full malware scan (Wordfence, MalCare, Sucuri) and rotate all salts, database passwords, and admin passwords.
