Steps to resolve “W3 total cache error: some files appear to be missing or out of place“.

Although W3 Total Cache has been removed from your WordPress Dashboard you still have files associated with the plugin located on your server. The error message states that the files need to be removed. Follow these steps and be free from the shackles of the error associated with this display

  1. Access the wp-content folder of your WordPress installation by FTP and delete the following files:
    • advanced-cache.php
    • db.php
    • object-cache.php
    • w3-total-cache-config.php
wp cache from cpanel
  • Locate the line in your wp-config file and change the true to false as seen here. {define('WP_CACHE', true); // Added by W3 Total Cache} You may delete this line if need be but changing to false fixes the issue instantly
  • Delete the W3 Total Cache plugin folder that you will find in the «… / wp-content / plugins /» folder
  • You can make a copy of the .htaccess file and then delete it.
  • Go to “Settings -> Permanent link” in the WordPress administration and save the changes without modifying any settings, in this way WordPress regenerates the .htaccess file, in this case only with what WordPress needs.
  • Reinstall the plugin from scratch and configure it to the specifications you need.

Now you can clear up the previous installation—complete with all of its mistakes—and start again with a fresh installation that is ready to speed up your website.
