 * Be careful about upgrading to the “Pro” version. If you roam this support thread
   you will see very unhappy customers who aren’t getting support of any kind.
 * Why not just save yourself the headache and enable pro and/or enterprise features
   by adding one or both of these lines into your wp-config.php file and be done
   with it ;P :
 *     ```
       define('W3TC_PRO',true);
       define('W3TC_ENTERPRISE',true);
       ```

 * Thanks for your answer. As suggested, i activated the pro version and activated
   the Fragment Cache so as not to cache the whole page but i’m getting the following
   error :
 * “Unable to execute”
 * Here is my php code :
    <?php echo ‘Cache The time is ‘.date( ‘H:i:s’, time() );//
   put time in cache ?> <!–mfunc <?php echo W3TC_DYNAMIC_SECURITY; ?> –> <?php echo‘
   The time is ‘.date( ‘H:i:s’, time() ); //not cached ?> <!–/mfunc <?php echo W3TC_DYNAMIC_SECURITY;?
   > –>
