I was developing a GWT application with a PHP backend. Everything was in order during development. I developed my GWT application from my website and everything worked correctly and interacted correctly with php.
However, when I compiled the GWT application and placed it in the same place where my original GWT application was and tried to run it, the interface appears, but in any place where I need to interact with the server, it does not display the application error messages, which I install when my web application cannot communicate with the server
