  • Resolved Benoit77


    Hi there

    I just update the versus of W3tc, that’s give me some fatal error.
    So I use a backup of the website from my host, (back up before I did the update), I still got the same trouble : ( ! ) Fatal error: Call to undefined function wp_start_object_cache() in /wp-settings.php on line 79
    Should I clean the cache of wordpress? if yes where I can do it thrue the FTP, knowing that I have no more access to the website (frontend and backend), I’m a bit lost to putt back the website on line…
    Any help would be welcome.
    thanks in advance

  • look in your wp-config.php:
    /** Enable W3 Total Cache **/
    define(‘WP_CACHE’, true); // Added by W3 Total Cache

    set it to false if W3TC isn’t installed anymore.

    Did you restore the database as well? Or just the filesystem? Database may need to go back to previous version.

    Thanks for the feedback!!
    Unfortunaly, still doen’t work, I restore the database, and by the occasion a new time the filesystem, still the sames troubles. I look up at the wp-config.php and define WP_CACHE to false too.
    I will try to disconnect the plugin with phpMyadmin in case of…

    Finally I find the way :

    1. I delete everything from the plugin :
    2.delete everything on the database with the terms W3C
    3. I replace the folder Wp-includs by a new one

    And now that’s works!! thanks for your help!
