To use a different port: Change the port in server.php: php $wsWorker = new Worker('websocket://0.0.0.0:2346', $context); Change the port in ns-chat.php: php $ws_port = 2346; You can check and change the port in chat-ui.js: js const port = nschat_data.wsPort || 2346; If the port is closed, then open a new port on your server’s firewall: bash sudo ufw allow /tcp sudo firewall-cmd --permanent --add-port= /tcp sudo firewall-cmd --reload sudo iptables -A INPUT -p tcp --dport -j ACCEPT sudo iptables-save > /etc/iptables/rules.v4 Database Tables The plugin creates and uses the following tables: wp_ns_chat_dialogues wp_ns_chat_messages wp_ns_chat_users Tables are created and populated automatically on plugin activation. User Synchronization Initial migration of all users from wp_users to wp_ns_chat_users on plugin activation. New registrations are handled by: php add_action('user_register', 'ns_chat_add_user_on_registration'); Profile updates are synced via: php add_action('profile_update', 'ns_chat_update_user_data'); You may bind these functions to custom hooks based on your app’s logic.
