# Mashup - Blank Spotfire

In the [Mashup mode](/public/docs/connector-spo-pp-swapp-guides-open#mashup-mode), when closing the current Spotfire document using the Spotfire menu, Spotfire becomes blank. It can also happen when opening a new document using the Spotfire menu.

## Details

This behavior is due to the fact that the Mashup Single Sign-On (SSO) session becomes invalid when closing the document or opening a new one. As a result, Spotfire cannot reload the document and the iframe containing Spotfire becomes blank.

## Resolution

There is no direct solution to this issue, as Mashup mode is designed this way: the application included in the Mashup is responsible for managing the Spotfire document lifecycle. It is therefore recommended that you avoid closing the document or opening a new one using the Spotfire menu when using the Mashup mode. For instance, if you are using the SWAPP application, you must use the [SWAPP menu](/public/docs/connector-spo-pp-swapp-references-features#the-swapp-menu) to manipulate documents.
