Web App displaying blank page only

[gopalverma1]

Sir,
i uploaded the demo project to a shared server, but it only showing blank white page, i modified the database connecting code to production

    if (!IsLocal()) { // Not local (Production)
       $info["host"] = "locahost";
       $info["user"] = "a47f7db4_demo2024";
       $info["password"] = "a47f7db4_demo2024";
       $info["dbname"] = "a47f7db4_demo2024";
    }

and in Advanced Setting : Environment => Production
Also Enabled debug => but showing only blank page

Even i contacted the provider regarding this, they informed no error in the log.

sir, anything i need to modify, for production

1. You should enable Debug and check your own log file on the production server.
2. You may change back to "development" mode for debugging, or you may read Enviromment to check what you should enabled for debugging in production environment.

In addition, make sure you have also configured your php.ini file, to display errors (and log errors if necessary):

error_reporting (int) - set it to E_ALL
display_errors (string) - set it to On
log_errors (bool) - set it to On
error_log (string) - set it to a log file on your server, e.g. "my/path/php_errors.log" (change "my/path" to your real path), the file should be writable by the web server's user. Note that this is error log by the php.exe, NOT same as log files (by PHP scripts) above.
