Error while saving

[RMIC]

Hello,

our SP-Forms version: 2.9.1

When saving the forms, the following error occurs:

Microsoft.SharePoint.ApplicationRuntime.SafeControls+UnsafeControlException: Ein Webpart oder Webformular-Steuerelement auf dieser Seite kann nicht angezeigt oder importiert werden. Der Typ 'FormsDesigner.Sharepoint.FDDataFormWebPart, FormsDesigner.Sharepoint, Version=2.0.0.0, Culture=neutral, PublicKeyToken=1c140246cb6fd531' wurde nicht gefunden oder ist nicht als sicher registriert.

Thus, we can not use SP Forms forms. Why is it?

Thank you for your help!

Dear RMIC,
Please, make sure to deploy solution in the Central Administration. If it already is, please, check the status, and if necessary try to re-deploy it.

Hello Nikita,

in a redeploy existing forms are not lost?

Thank you!

[Nikita Kurguzov]

Dear RMIC,
No, the forms will remain.
