------ Solution --------------------

Download the latest Smarty: http://smarty.php.net/
Latest version: 2.6.18
Decompress the package and rename the libs directory in the directory to smarty. copy the libs directory to your website directory, and create the templates and templates_c directories under the website root directory.
Create test. php with the following content:

 Include_once ('./Smarty. class. php'); $ smarty = new Smarty ();
$ Smarty-> template_dir = "./templates"; // template storage directory
$ Smarty-> compile_dir = "./templates_c"; // compile the Directory
$ Smarty-> left_delimiter = "{"; // left delimiter
$ Smarty-> right_delimiter = "}"; // right delimiter
$ Smarty-> assign ('test', 'OK ');
$ Smarty-> display('test.html ');
?>
Grant templates_c permissions to 755

Create test.html in the templatesdirectory:
 
 
 
 
{{$ Test }}
 
 
Open test. php. if OK is displayed, your smarty is successfully installed!

------ Solution --------------------
Make sure that the smarty has been correctly configured... I don't know what version your smarty is.
