Support » Plugin: W3 Total Cache » Remove memcached from W3TC by hand

  • Resolved danielbittar


    Hi there people!

    I was using Memcached in W3TC in a previous provider. Now I’m in a new provider and I’m getting the following error when trying to login to WordPress Admin Panel:

    Fatal error: Class 'Memcache' not found in /home/danielmb/public_html/ on line 38

    I need to disable Memcache from any configuration it is or database location but I’m not being able to do so. And I can’t login to the Admin Panel to do it there.

    How do I disbale it?

    Thanks a lot,
    Daniel Bittar.

  • Two things to try:

    First, in wp-config.php, set WP_CACHE to false or add the following to your wp-config.php:
    define(‘WP_CACHE’, false);

    Second, make a backup of your database & then run this query through a database tool from your ISP (like ‘phpMyAdmin’):
    UPDATE wp_options SET option_value = ‘a:0:{}’ WHERE option_name = ‘active_plugins’;

    (for more info on that query,

    wp-config.php is probably the best method. An alternative method is to rename the W3 Total Cache configuration file. It is named w3tc-config/master.php in the current version.

    Hi there again, people!

    Well, I tried the first option and it didn’t work. However I didn’t try the second one. I just regained access to my old server, disabled the cache and did the migration again.

    Anyways thank you everyone.
