When working with Screen Templates you may see the following warning message: The Themes are not compatible. The final Screen may look different than the preview. To use this Screen Template, you need a module with a Theme based on (module name)(theme name). This means that your module and Screen Template are not compatible, which may cause the final page not to display correctly.

If you are using one of the built-in Application Templates:

Select a compatible Screen Template. All default Screen Templates are compatible with the built-in Application Templates.
Create your own Screen Templates that are based on your custom Theme.

If you are using one of the Silk UI Web Application Templates inherited from OutSystems 10 (Lisbon, Dublin, Liverpool, Vanilla, and Website) or the London Theme based Application Template, Web Application:

Migrate your web application to OutSystems UI Web framework. The default Screen Templates that come bundled with OutSystems 11 are not compatible with the Silk UI nor with the London Theme.
Create your own Screen Templates that are based on your custom Theme.

If the Screen Template was compatible with your module, but now it's not:

Revert the changes you did to the module Theme.
Check if the correct Theme is set in the Default Theme property field of your Module/Flow.
