Syntax errors in template files can cause a page to be unable to render completely.

Other common causes include:

  • Using features of Smarty that have been removed in the upstream Smarty package
  • A custom or third party module that is incompatible
  • Using PHP code blocks in your template without the Allow Smarty PHP Tags setting enabled (go to Setup > General Settings > Security to enable it)


If you see a blank page after making a change to a template file, check the Activity Log in Utilities > Logs for any logged error message.

If you don’t find anything in the activity logs, switching to a different template is an easy way to determine if the issue is with your template or something else.
