各位大侠，求助个问题：
以下是我把程序装上去后访问首页出现的错误提示。百度了下好像是说不能设置成相对路径（就是目录前加.）
但我不懂thinkphp，希望各位大侠帮助解答下，万分感谢！

Warning: include(/xxx/./index.tpl.php) [function.include]: failed to open stream: No such file or directory in /xxx/Lib/Merchants/Index/index.class.php on line 5

Warning: include() [function.include]: Failed opening '/xxx/./Merchants/Index/index/index.tpl.php' for inclusion (include_path='.:/xxx/apache_php-5.2.17/lib/php') in /xxx/Lib/Merchants/Index/index.class.php on line 5

附index.class.php内容：
<?php
bpbase::loadAppClass('base', '', 0);
class index_controller extends base_controller {
public function index() {
include $this->ShowTpl();
}
public function price() {
include $this->ShowTpl();
}
}

?>
