Accessing static property JCache::$_handler as non static in C:\xampp\htdocs\Myschool\libraries\joomla\cache\cache.php on line 420

You have to make a few modification in php.ini, look for "error_reporting = E_ALL | E_STRICT" and remove value "E_ALL | E_STRICT", should look like "error_reporting = " (without quotes) then restart server
