Hello, I’m trying to add the ExcelImporter Module to my application. But I receive the warnings (see the picture) that layout and placeholder Atlas_UI… are no longer existing. I didn’t delete anything. Does anybody have an idea what the error might be? Kind regards!
This is because Mendix 9 comes with a new version of Atlas UI and the imported module uses older layouts. To resolve this you can edit the layout of those pages and select a layout of Atlas which is available. It will solve your errors.
