Pages displaying blank ONLY when Theme Developer module turned on i have a situation where the theme developer module, when turned on, is causing some pages to display as the white page (of death). it's probably because i've been doing tutorials, learning how to override theme functions and probably at one point had some errors. but there errors have been cleared up, but the pages display as blank pages ONLY when that module is turned on. it's as if it has it's own cache???, 

anyone know how to remedy that?, i need module to work.
This might be due to version compatibility with Simplehtmldom module. 

Download this library and install in your sites/libraries files. 

This is taken from modules page,


  NOTE: Currently, Theme Developer does not work with the latest version of simplehtmldom API. You must use simplehtml API version
  7.x-1.12 if you want Theme Developer to function properly.


OR if that is not the case you can try putting this snippet end of  the settings.php file, this snippet will show error message on the browser while loading page instead of WSOD. and you can put your error message here in question and elaborate it.

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