WordPress: Updating failed. You are probably offline.

The block editor’s save request to the REST API failed — network blip, REST API blocked, or the server returned an error/HTML.

Seen on: WordPress

Meaning

The editor saves via /wp-json/. Security plugins, Cloudflare/WAF rules, REST disabled for some users, expired login or server errors show this generic message.

Common causes

  • REST API blocked (security plugin, WAF, host)
  • Login session expired
  • Server error (500) during save
  • Actual network interruption

⚡ Quick fix

  1. Check the Network tab for the failed /wp-json/ request and its response
  2. Test Site Health → REST API
  3. Whitelist /wp-json/ in security/WAF rules

Detailed fix by platform

Shell

  1. curl -s https://example.com/wp-json/ | head -c 200

How to diagnose

  1. Request — Status and body of the failed save
  2. REST — Site Health status
  3. Session — Still logged in?
