WSOD however WP_DEBUG not giving any errors

I’m working WordPress on a WAMP stack and I am attempting to debug a WSOD error, which I feel is a PHP error, as I’ve tried disabling all my plugins and themes and they are not the issue.

I’ve acquired this in my wp-config :

 outline('WP_DEBUG', true);
 if (WP_DEBUG) {
      outline('WP_DEBUG_LOG', true);
      outline('WP_DEBUG_DISPLAY', true);
      @ini_set('display_errors', 0);
 }

which I discovered on-line. After I reload the web page I do not get any error messages, and once I test for wp-content/debug.log it would not exist. I can not discover any error logs anyplace else both. How can I discover out what goes improper?

Thanks for any assist.
