Strict Standards: Accessing static property JCache::$_handle - Joomla error

How about fixing the error instead of muting the error message?

Just go to line 419 in cache.php and change all occurences of $this->_handler to JCache::$_handler:

Code:

   public function &_getStorage()
   {
      if (!isset(JCache::$_handler)) {
         JCache::$_handler = JCacheStorage::getInstance($this->_options['storage'], $this->_options);
      }
      return JCache::$_handler;
   }
