We have checked your server.
All Java libraries and configs seems to be correct, but database.yml file is 0 bytes length. So WCS cannot authorize web interface and CLI users, and no server REST hook applications defined.
Please restore this file from your own backup if possible, or put default database.yml file that we've sent you by email to /usr/local/FlashphonerWebCallServer/conf folder and restart WCS
With default file, you will have:
- admin:admin and demo:demo users
- default REST hook applications
Also, we recommend you to clean WCS logs:
1. Stop WCS
2. Execute the command
rm -rf /usr/local/FlashphonerWebCallServer/logs/*
3. Start WCS
Then, please check server functions.
Please also note that English speaking clients should post their questions to English forum section.
