我删除smarty缓存后出现这个：

Warning: Smarty::include(./templates_c/default/\%%99^993^993A0A9C%%default.html.php) [smarty.include]: failed to open stream: No such file or directory in F:\wwwroot\wwwroot\wangyingjie\wwwroot\i_web_include\libs\Smarty.class.php on line 1258Warning: Smarty::include() [function.include]: Failed opening './templates_c/default/\%%99^993^993A0A9C%%default.html.php' for inclusion (include_path='.;C:\php5\pear') in F:\wwwroot\wwwroot\wangyingjie\wwwroot\i_web_include\libs\Smarty.class.php on line 1258我的smarty配置为：
$smarty = new Smarty();
$smarty->template_dir="./templates/default/";
$smarty->compile_dir="./templates_c/default/";
$smarty->cache_dir=CACHE_PATH;
$smarty->left_delimiter="{*";
$smarty->right_delimiter="*}";
$smarty->caching=false;
$smarty->clear_cache('default.html'); //清除index.html的缓存
