Smarty shows whitepage most time

Hi I have an application which is developed used Smarty 2.6.26 template engine.

The application was working fine till last week. Now I am getting a strange scene. Sometimes or frequently my sites displays whitepage instead of my website contents. Cleaning the templates_c directory fixes the issue. But this happens on a continuous bases. I have not enabled the smarty caching in my application.

Any help highly appreciated.

Things I have already tried

$smarty->compile_check = false; ( changed to false from true )

My Current Smarty settings

define('SMARTY_DIR', 'Smarty/libs/');

require_once(SMARTY_DIR . 'Smarty.class.php');

$smarty = new Smarty;

$smarty->compile_check = false;

$smarty->debugging = false;

$smarty->template_dir = 'view';

$开发者_开发知识库smarty->compile_dir =  'templates_c';

You can see if it's compile caching by setting force_compile.

$smarty->force_compile = true;

This should only be used for debugging. I have the same problem as you when I am working in my development environment when I try to refresh the browser to see the changes and the changed file has not finished copying to the test server.
