    hi there

    i’m on a migration, and i see in the error log that your plugin makes problems:

    [09-May-2018 09:27:34 UTC] PHP Fatal error: ob_start(): Cannot use output buffering in output buffering display handlers in C:\xampp\htdocs\wp-content\plugins\w3-total-cache\Generic_Plugin.php on line 88

    or is the problem that “wp-config.php” will be cached too, so it’s useless to change that setting?

    1. It doesnt cache wp-config.php

    2. WP_CACHE in wp-config.php is a requirement by wp when a 3rd party cache program wants to override WP’s default. It tells wp to look for advanced-cache.php in wp-content directory.

    3. Have you checked your php’s disable_functions list? Maybe your ISP is blocking access to ob_start() function. You can do a ini_get(‘disable_functions’); and parse through it or check your php config for the line. If ob_start() is in it then that is your problem and will need to contact your isp to allow it to be used.
