How do I debug a WordPress website?

We recently had a client who experienced a WordPress site suddenly not working. It was loading a blank white screen in Firefox and a 500 Error in Google Chrome. Now if I know a bit of HTML and CSS but if my WordPress site is not loading, how do I fix a white screen on a WordPress website? 

  1. Open your wp-config.php file, add these lines near the middle of the file.
    define(‘WP_DEBUG’, true);
    define(‘WP_DEBUG_LOG’, true);
    define(‘WP_DEBUG_DISPLAY’, false);
  2. This outputs the files to debug.log in the /wp-content folder.
  3. Visit you site again, and now error is written into /wp-content/debug.log.
  4. The resulting error with TimeStamp will tell you the exact location and a list of reasons why WordPress is not loading.

In this case, for this client, there was an accidental deletion of a character in the functions file.
