To debug then I opened the error log to and this was the PHP error: FastCGI sent in stderr: “PHP message: PHP Warning: Invalid argument supplied for foreach() in /wp-content/plugins/fb-instant-articles/wizard/class-instant-articles-wizard.php on line 116” while reading response header from upstream, client: X.X.X.X, server: dev.test.com
