+   ```bash
+   # Cek PHP version yang digunakan
+   php -v
+   
+   # Cek socket path (biasanya di /tmp/php-cgi-XX.sock)
+   ls -la /tmp/php-cgi-*.sock
+   ```
+   
+   Setelah edit, klik **Save** dan **Reload** nginx.
+   
+   **Atau copy file `nginx.conf.example` dan sesuaikan path PHP socket.**
