Causes and fixes

What you see	Cause and fix
`widget.js` never loads	Chat is off or was not saved in `Live chatChat settingsAppearance`, the tag carries `data-chat="false"`, or analytics itself is not sending. Check the installation first.
`widget.js` loads, no bubble, narrow window	Hide bubble on mobile is on. It hides the bubble when the window is narrower than 640 px or the browser identifies as a phone. Widen the window or turn the setting off.
`widget.js` loads, no bubble, any size	The page’s domain is not registered on the SDK code page. The chat service then answers as if chat were off; nothing is shown and no error appears.
Console shows a CSP error	Your Content-Security-Policy must allow the chat host for the script and the conversation window, and the chat gateway for the live connection. The error names the host to add.
Bubble shows, the window opens as a message form	Nobody is online and no AI assistant is answering, or this month’s conversation quota is used up. See what visitors see when nobody is online.

Still nothing after changing a setting?

Settings are read when the page loads, so reload the page after every change. A page cache or CDN can keep serving an older copy of the HTML; that matters only if you changed the script tag itself.
