zlib compression is detected by WP Super Cache though it’s disabled

    Hello,

    This message appears at the top of the plugin’s settings pages:

    #start

    Zlib Output Compression Enabled!

    PHP is compressing the data sent to the visitors of your site. Disabling this is recommended as the plugin caches the compressed output once instead of compressing the same page over and over again. Also see #21 in the Troubleshooting section. See this page for instructions on modifying your php.ini.

    #end

    I checked my server’s settings, zlib output is turned off and there’s no php.ini file that I could access to. What should I do?

    Thanks in advance for your help.

    Best regards,
    évelyne.

  • I’m getting this too. I added this to my php.ini file:

    `zlib.output_compression = 0
    zlib.output_compression_level = -1`

    I’m still getting the message with PHP v7.2.

    Me too. Zlib output is off in my php.ini, yet message persists.

    wp super cache zlib output compression enabled
    solution
    Go to cPanel
    MultiPHP INI Editor
    Basic Mode
    Configure PHP INI basic settings
    Select the home directory or a domain’s document root to open the corresponding PHP configuration (your domain)
    zlib.output_compression – set disabled

    Sa?a

    It’s possible that you need to edit .user.ini in home directory instead of php.ini file. It depends on hosting and PHP version.

    Anyway, you should upload simple phpinfo.php (<?php phpinfo();) somewhere to verify status of zlib output compression.

    I’ve found adding ini_set('zlib.output_compression', 0); to the wp-config file works best. Otherwise, adding zlib.output_compression = off to php.ini had no effect since it was already set to off.

    Viewing my phpinfo.php file with <?php phpinfo(); ?> stated:

    `
    zlib.output_compression: Off
    zlib.output_compression_level: -1
    lib.output_handler: no value
    `

    Thx @polyfade that solved my problem!
