Hi,

sorry for the delay in my response.

The wp-config.php contains nothing unusual (database settings, authentification / security setup, debug mode is disabled):

define('DB_NAME', '[redacted]');
define('DB_USER', '[redacted]');
define('DB_PASSWORD', '[redacted]');
define('DB_HOST', '[redacted]');
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');
define('AUTH_KEY', '[redacted]');
/* ... */

$table_prefix = 'wp_pixx_';
define('WP_DEBUG', false);
if ( !defined('ABSPATH') )
	define('ABSPATH', dirname(__FILE__) . '/');
require_once(ABSPATH . 'wp-settings.php');

/**
 * Include tweaks requested by hosting providers.  You can safely
 * remove either the file or comment out the lines below to get
 * to a vanilla state.
 */
if (file_exists(ABSPATH . 'hosting_provider_filters.php')) {
	include('hosting_provider_filters.php');
}

The referenced “hosting_provider_filters.php” contains code to disable xmlrpc-pingback.

During the last week, I tried enabling the Falcon engine again with my attempted fix in place (adding SetEnv no-gzip dont-vary to the htaccess file).

So far, it’s working without any issues. Maybe there had been some caching issues which played into this…

Again (for people experiencing a similar behavior), my .htaccess file looks like this:

#WFCACHECODE - Do not remove this line. Disable Web Caching in Wordfence to remove this data.
#...
#Do not remove this line. Disable Web caching in Wordfence to remove this data - WFCACHECODE

RewriteEngine on
# ... (Domain rewrites)

# THE LINE I ADDED:
SetEnv no-gzip dont-vary

# Use PHP5.4 as default
AddHandler application/x-httpd-php54 .php

# BEGIN WordPress
#...
# END WordPress

# ... (MIME-Types)

# Start CloudFlare:journeyofcode.com rewrite. Do not Edit
# ...
# End CloudFlare rewrite.

I don’t know the exact difference between my addition and the lines added by Wordfence:

SetEnvIfNoCase Request_URI \.html_gzip$ no-gzip
SetEnvIfNoCase Request_URI \.xml_gzip$ no-gzip

So far, it seems to do the trick, however. I’ll update here if issues start appearing again.
