W3 Total Cache has its own compression features built in to it. These do not seem to play well with enabling zlib compression in your PHP configuration. Helpfully, the user interface will prompt you to resolve the issue if it is enabled:

W3TC

If you decide to use W3 Total Cache, make sure your php.ini file includes:

zlib.output_compression = off

On Ubuntu using the basic LAMP stack, you would need to edit /etc/php5/apache2/php.ini Make sure to restart Apache after making the change:

sudo service apache2 restart
