The “AI is not configured” notice.

Cause

The selected provider has no saved API key. Or the stored key failed decryption. Decryption failure typically happens when your site’s AUTH_KEY / AUTH_SALT values changed after the key was stored (for example after a migration or a security reset of wp-config.php).

Fix

1. Open SEO & Chill → Settings → AI.
2. Paste your API key again.
3. Click Test and save. The key is saved only when the test works.

Keys are encrypted with your site’s auth salts. Rotating those salts is good security practice. Just re-save your API key afterwards.
