 * After update I can’t seem to activate the plugin.
    This is the error:
 * Warning: require_once(/home/mysite/public_html/wp-content/plugins/w3-total-cache/
   lib/W3/Plugin/CloudFlare.php): failed to open stream: No such file or directory
   in /home/denar/public_html/wp-content/plugins/w3-total-cache/inc/define.php on
   line 1449
 * The file is really missing. I’ve downloaded the package and the archive is also
   missing such file in that path.

 * Went back to 0.9.3 for now. Seems to be a lot of Cloudflare related errors in
   this new version.

 * Had the same problem on 2 WP sites. Fixed the issue by restarting apache immediately
   after updating W3TC plugin – this cleared my APC cache. I’m using APC for PHP
   opcode, W3TC db/object caches. HTH.
 * Btw, 0.9.4 seems to have moved CloudFlare support to an “extension”. I am no 
   longer enabling CloudFlare from within W3TC, will manage it directly on cloudflare.
   com. Don’t want to break my sites with future upgrades.

 * I haven’t updates yet. rsubr can you explain what you mean when you said CloudFlare
   is being to an extension.

 * rsubr,
 * You are correct. Thank you. It was the APC cache.

 * [@rsubr](https://wordpress.org/support/users/rsubr/). I am thinking of doing 
   the same thing as far as only using the cloudflare interface. So do you use the
   combine functionality in W3TC for js and css and then minify with cloudflare?
   Just curious about the setup and how your site speed is that way.
