If you see the error “Incorrect nonce” when trying to submit a new location, it usually means the page has been cached for too long. Nonces in WordPress are time-sensitive security tokens — when a cached version of a page is older than the nonce’s validity period, the submission will fail.

✅ How to Fix It (LiteSpeed Cache)

If you’re using LiteSpeed Cache, follow these steps:

1. In your WordPress dashboard, go to LiteSpeed Cache → Cache → TTL.
2. Find the setting Public Cache TTL.
3. Set this value to 12 hours or less.
4. Save your changes.

This ensures that no cached page is served for longer than a nonce remains valid, preventing the “Incorrect nonce” conflict.

💡Tip

If you’re using another caching plugin, look for a similar setting that controls cache expiration time or TTL (Time to Live), and set it to 12 hours or lower.
