3CX Live Chat Updates: Migration and Troubleshooting
Update an older 3CX Live Chat installation safely. Check the account URL, routing, widget display and duplicate scripts before returning it to service.
Reviewed 27 September 2026.
Use current setup guidance, not old launch terms
Older 3CX announcements described products, trials and account limits that may no longer match your installation. Confirm the current account and deployment model before following old screenshots. This guide covers migration and troubleshooting; our 3CX review covers whether the service fits.
The current live-chat manual is the starting point for account configuration and the WordPress chat URL.
Record the working configuration
- Back up WordPress and note the installed integration version.
- Record the 3CX environment and responsible administrator.
- Document the assigned agents, queue, hours and offline behavior.
- Check whether a widget script also exists in the theme or tag manager.
- Keep a contact form available during changes.
Match the widget to the right account
Copy the intended live-chat URL from the correct 3CX configuration. Do not combine a trial account’s URL with agents in another environment. Save, clear relevant caches and test while logged out.
Check the permitted website configuration and whether the integration is loading once. A duplicate widget can result from installing both a plugin and manual script.
Troubleshooting table
| Problem | Investigate |
|---|---|
| No widget | Display settings, script errors and blocking rules |
| Widget but no agent response | Routing, availability and the account URL |
| Two widgets | Plugin, theme and tag-manager installations |
| Mobile obstruction | Position and overlap with other controls |
Verify before closing the migration
Complete a conversation from visitor to agent and back. Test offline behavior, another browser and a phone. Confirm the expected people can access records. Keep the previous configuration until the new path works, and document the final account and routing details for the next administrator.
