 * Did you develop your React app with ReactPress? Otherwise you will need to do
   some adjustments in your `vite.config.js` to have make your app work with ReactPress.
 * I would be best, if you would create an app with the quickstart tutorial and 
   look how the configuration changes and appy that to your app.

 * Hmm, the React app was developed separately. I dont use vite for my React app.
   but I could run my react app with fresh WP project on my local dev environment.

   Could it be because there is a conflict between plugins?

 * I don’t think it is conflict between plugins.
 * How is your React app set up? Did you use create-react-app or a custom webpack
   configuration?
 * The thing is, ReactPress expects a Vite or cra environment and behaves accordingly.
 * Otherwise, chances are that ReactPress won’t load your files correctly. If you
   can tell me more about your React setup, I can try to guide you through how we
   can trick ReactPress into thinking your React app is build with one of the mentioned
   environments.
 * Important to know is where the release build is located and how the app is loaded
   into the HTML page.
