    On a fresh install of W3 Total Cache on WordPress 4.7.1, as soon as I install and navigate or install and activate, I get this error:
    Fatal error: Uncaught Error: Call to undefined function W3TC\json_decode() in /var/www/clients/client1/web1/web/wp-content/plugins/w3-total-cache/Config.php:38 Stack trace: #0 /var/www/clients/client1/web1/web/wp-content/plugins/w3-total-cache/Config.php(359): W3TC\Config::util_array_from_file('/var/www/client...') #1 /var/www/clients/client1/web1/web/wp-content/plugins/w3-total-cache/Config.php(108): W3TC\Config->load() #2 /var/www/clients/client1/web1/web/wp-content/plugins/w3-total-cache/Dispatcher.php(16): W3TC\Config->__construct() #3 /var/www/clients/client1/web1/web/wp-content/plugins/w3-total-cache/Dispatcher.php(24): W3TC\Dispatcher::component('Config') #4 /var/www/clients/client1/web1/web/wp-content/plugins/w3-total-cache/Mobile_Redirect.php(16): W3TC\Dispatcher::config() #5 /var/www/clients/client1/web1/web/wp-content/plugins/w3-total-cache/Dispatcher.php(16): W3TC\Mobile_Redirect->__construct() #6 /var/www/clients/client1/web1/web/wp-content/advanced-cache.php(31): W3TC\Dispatcher::component('Mobile_Redirect') in /var/www/clients/client1/web1/web/wp-content/plugins/w3-total-cache/Config.php on line 38
    I have to SSH in and delete /wp-content/plugins/w3-total-cache to get the website working again.

    Does the json module show up in your phpinfo() output?

    Although it should be installed and compiled into PHP by default, it seems the json extension isnt being picked up. When you type php -m in CLI do u see json mentioned in the list?

    If you have cPanel installed jump to the PHP Version section and enable the json extension.

    Indeed json was not listed in php -m. 51 other modules were listed, but json is not included by default with PHP 7.1. I used yum to install php_json and now W3-Total-Cache works. WordPress and the other 27 plugins in this small site did not require json to work correctly.

    I urge the developers that a test for json availability be added since it is required for this plugin and it is not included in PHP 7.1 by default.

    Thanks very much for your help!
