So if you happen to update your site from WordPress 4.5.3 to 4.6 or newer and your site stops working.  If it is giving too many redirects and is not putting anything in the sites error_log file you may want to take a look at what you have entered into the site_url and home_url spots of your database.  If you happen to like capitalizing your URL’s in these spots it seems to be causing a constant redirect causing your site not to load.
