 * Hi [@jolinps](https://wordpress.org/support/users/jolinps/),
 * – make sure that in the “Firebase App ID” and “Firebase App Secret” fields there
   are no spaces.
    – make sure you’ve got the correct “Firebase App Secret” as indicated
   in the documentation: [https://yithemes.com/docs-plugins/yith-live-chat/02-settings.html](https://yithemes.com/docs-plugins/yith-live-chat/02-settings.html)
 * If the problem persists try to create a new Firebase App.
 * Let us know.
 * Best regards.

 * Hi,
 * Already check everything or made the new Firebase App.
    The result is still the
   same.
