    The message below is causing problems

    “Either the PHP configuration, web server configuration or a script in the WordPress installation has zlib.output_compression enabled.
    Please locate and disable this setting to ensure proper HTTP compression behaviour”

    How did I diagnose that it is this plugin creating the error? I simply took time to switch on and off every plugin and as soon as I deactivated W3 Total Cache, the error then disappeared and when i reactivate, the warning then returns.

    The page I need help with: [log in to see the link]

    Hello @stanleyuroy11

    Thank you for reaching out and I am happy to assist you with this.
    As the notification suggests, zlib.output_compression is enabled, and that conflicts with the Gzip compression used in Performance>Browser Cache.
    zlib.output_compression, when enabled, compresses all responses in Apache. We use PHP to compress the page and store the compressed page in a file to be accessed directly from Apache so we don’t have to build the page anymore. That’s the difference. Your PHP configuration doesn’t allow us to compress the page.
    So you need to remove php_flag zlib.output_compression on and make sure that mod_deflate is installed/enabled on your server so you can use Gzip compression.
    I hope this helps and let me know if you have any other questions.
    Thanks!
