You've upgraded your installation, but now your custom client area template is no longer working.

Then you've come to the right place. Let's start at the beginning...

Why does this happen?

A blank or partially rendered page indicates a fatal PHP error is occurring which stops the execution from being able to continue. This can be caused by a number of reasons, most commonly:

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

For more detailed information, please see Blank or Partially Rendered Pages.

Check the Logs

The first place to check any time you encounter an error of this nature is the activity log. This can be acccessed by navigating to Utilities > Logs > Activity Log within the admin area. All errors encountered by the Smarty templating engine are logged here, and should help pinpoint the exact template and section of code that is causing the problem.

Try a Different Template

If you don't find anything in the activity logs, try switching to one of the default templates to rule out issues with custom or third party code. If changing to a different template allows the client area to load successfully, then you know the issue is your template. If it does not, then your issue is more likely related to a module or hook.

To change the template your system is set to use, navigate to Setup > General Settings and choose one of the default templates in the Template setting found on the first tab of the settings.

Check Your Templates for Legacy Smarty Functions

Most custom templates won't need any updates to be compatible with newer versions of Smarty, but those features only available in Smarty 2 will need to be migrated to ensure a smooth transition to the latest version.

For more information on exactly what's changed, please refer to our Version 6 Template Migration Guide.
