# Problems with cache

 * I have a site [http://www.magicasdemae.com.br/](http://www.magicasdemae.com.br/),
   and I installed w3ct. On November 18 I did an update of the plugin and this broke
   my site.
 * I uninstalled the plugin on this day.
 * But over 2 months later, I’m still in trouble. When I enter the site by the main
   address, sometimes the current version appears (January 2017), but sometimes 
   the November 2016 version still appears.
 * I tried installing w3ct one more time, to try to clear the cache and fix the 
   problem. But I can no longer install the plugin on my site. The message appears:
 * “Fatal Error. Please update your PHP.” W3 Total Cache requires PHP version 5.3
   or above ”
 * The detail is that I’m using PHP 5.6. That is, until the error message is in 
   trouble.
 * I do not know what to do to fix the problem.

 * Are you really sure you are on php 5.6?

 * _“Fatal Error. Please update your PHP.” W3 Total Cache requires PHP version 5.3
   or above ”_
 * That right there is very fascinating since you say you have 5.6 installed.
 * 1. Do you have terminal access into your website directory? If so jump in and
   type: “php -v”. I’m intrigued what the results say.
 * 2. So, despite w3tc not being installed you some times see an old version of 
   you site being served? Are you running your site through a distributed CDN service?
   It’s possible one of their remote points on the CDN have not updated their cache
   of your site (nothing to do with w3tc) and possibly serving that. Have you cleared
   your CDN cache?
 * 3. I assume you no longer have any cache plugin running on your site. So do you
   see the file: _/wp-content/**advanced-cache.php**_ or _/wp-content/**object-cache.
   php**_ or the line `define('WP_CACHE', true);` in your _wp-config.php_ file? 
   This might give us a clue if someone is serving a cache from your local side.
