Problem with new Version of Aspose.Cells 21.8

Hello Aspose-Team,

We tried to update Aspose.Cells (Version 20.6.6) and Aspose.Cells.GridWeb (Version 17.7) to 21.8
and get the following error-message when we open a GridWeb and type something in a cell.

We updated only the .dll’s

What can we do?
Has it something to do with the folder “aspose_client”?

Thanks in advance for your help
Matthias

@Matthias_Winzer,

We include some enhancements regarding Session modes in latest version of Aspose.Cells.GridWeb v21.9 (we released Aspose.Cells for .NET v21.9 today that includes this GridWeb version). Please try latest version of Aspose.Cells.GridWeb v21.9 with its latest resource files (acw_client folder). If you still find the issue, kindly create a separate simple VS.NET project (runnable), zip the project with its resource files and upload to some file sharing service (Google drive, dropbox, etc.). Share with us a link to download it so we could test and evaluate your issue on our end.
