这是错误：
Warning: require_once(/home/exhibit/public_html/includes/version.php) [function.require-once]: failed to open stream: No such file or directory in /home2/exhibit/public_html/includes/joomla.php on line 71
Fatal error: require_once() [function.require]: Failed opening required '/home/exhibit/public_html/includes/version.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home2/exhibit/public_html/includes/joomla.php on line 71
如何解决？
