When you get a white screen these are the common cause:
- Chevereto stopped execution due to a fatal error
In this case, you will only see a white screen with no data. Most likely is an error related to a missing library or things that you will need to fix in your server. In some cases, this is triggered when you don't upload some files to the server (script files).
- Your php.ini settings are not allowing to show errors
php.ini file settings could be restricting errors to be shown (display_errors = 0 mutes the output, log_errors = 0 disables error log).
In a production environment
is normal to do not display the errors in execution, instead, the errors are logged in the server's error_log file which will have all the needed information of error that just happened. If you don't have an error log file you should configure your server to store those logs.
