If the "Preview" button is disabled in Qodly Studio, it’s likely because the Web Server is not running.



How to Fix It:


  1. Go to the Run menu in the top menu bar of 4D.

  2. If you see "Start Web Server", click it to launch the web server.

  3. Once the web server is running, the Preview button should become available.

  4. Click Preview to launch your web project in the browser.
