Hi there! I work at Chatlio support. Would you be able to contact us at [email protected] and share the URL of your website so we can take a look and see why the widget is not displaying.
That should be all you need to do if you’ve installed the Chatlio plugin and added the WidgetID.
One other thing to check. Does your WordPress Website use some kind of Cache? If it does, you can try clearing that Cache.
Best,
