There are some PHP settings that can lead to WSOD. These are as follows:

  1. max_execution_time: Apparently, on WAMP, the default is 30 seconds, but some administrative pages may take longer than that to process and load.

Go to XAMPP/php/php.ini and change :

    max_execution_time = 360
  1. PHP Memory Limits: Another common reason for the WSOD is issues with memory limit.

    memory_limit = 128M

I guess you should be able to find the issue if you can come to know the error that is causing the problem, as the error reporting is by default turned "OFF" to avoid end user know the internal error for security and other purposes, so enabling the error on local or on dev server might help you out, try adding the following code in settings.php:

error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

Note:- Remove the above code from settings.php file once you are done with the development work.

Also check the errors/exceptions logged in the watchdog table in drupal at "/admin/reports/dblog":

Also please check this link: Blank pages or "white screen of death" (WSOD) for other possible solutions to WSOD.
