White background, black text – the simplest on earth : “error”!

I figured out the bug with enabling the debug (as suggested by David Kryzaniak):

define('WP_DEBUG', true);

Found the bug, it’s generating by any of three plugins. I renamed the plugins folder to plugins1, and it’s live again.

EDIT

Found a Tutorial on how to proceed on such error from Tuts+, anybody interested in :

There are issues discussed like:

  1. Checking Your Plugins
  2. Increasing the PHP Memory Limit
  3. Replacing the Theme
  4. Enabling Debug Mode
