How the PHP Web site changed the Linux post-template label does not parse is what happened

PHP website How to change the Linux after template label does not parse what is going on?
{epd::c (' site_name ')}

Is such a template label, the original with win system run is normal. After changing the Linux system, the running Web page is returned directly intact. I don't have to parse the label. What are you willing to do, I know it must be an environmental problem. But I don't know where it is. Is it a PHP environment or a system environment? What's the whole?
------Solution--------------------
1, confirm the project documents are all copy?
2. Did the PHP environment match successfully, Phpinfo (); Check it out.

------Solution--------------------
Is this a smarty template?
