Login Problem in Android App.

[talamkhani]

Hi,
I have installed LiveHelperChat 4.7 on a Debian server with ISPconfig installed on it on chat.domain.ltd on Nginx.
I downloaded the LiveChatHelper app from the Google Play Store and installed it on my Android phone.
When I log in via phone, I get the message "Login was not successful".

Through the troubleshooting I did, I found that the request reaches the server and the login form values ​​are posted to /modules/lhxml/checklogin.php.
Before checking the username and password, the value of $options['notifications'] is checked, and since the value 0 is sent, this condition prevents the login check from continuing.
if (!isset($options['notifications']) || !$options['notifications']) {
exit;
}

What causes this variable to have a value of zero?
How can I fix this problem?

I fixed the problem. Apparently webhooks should have been enabled in the settings/settings.ini.php file.
