Installation Guide (English)
- Download and add the files
Copy all files to the root directory of your website (via FTP, file manager or Git):
chat-widget.js
bot.php
get-messages.php
telegram-webhook.php
admin.php
config.php
- Configure config.php
Test the chat
Open your website in incognito/private mode (to simulate a new user). Click the chat icon (💬) in the bottom right corner. The bot should greet you first and ask for name, preferred language and contact info. Send a message — the bot replies instantly. Check if you receive a notification in Telegram from @BILOHASH_bot. Go to the admin panel: https://yourdomain.com/admin.php Password: admin123
Common issues and solutions
Chat window flickers or disappears → Delete the localStorage key bilohash_chat_session (F12 → Application → Local Storage). No message in Telegram → Verify that chat_id is correct (use getUpdates in browser). HTTP 500 error on admin.php → Check server error log (cPanel → Error Log). → Temporarily add ini_set('display_errors', 1); at the top of admin.php to see the error. Bot speaks wrong language → It auto-detects browser language. You can also manually select with flags in the chat (if enabled).
Extra tips
To clear all chat logs (for testing): delete all .json files in /conversations. Change Grok model in config.php for faster or more advanced responses. Protect admin.php with .htaccess (optional):
