I have Sitecore 8.2(update 1) site with WFFM 8.2. When i navigate to the Sample form folder sitecore/System/Modules/Web Forms for Marketers/Sample form and click on any form then i got error in popup:

Could not load type 'Sitecore.Form.Submit.ISaveAction' from assembly 'Sitecore.Forms.Core, Version=, Culture=neutral, PublicKeyToken=null'.

I have all latest dll and config files of WFFM 8.2 and this error i have faced after upgrading my Sitecore from 8.1 to 8.2.

Starting with version 8.1 Sitecore.Form.Core.Submit.ISaveAction interface has been moved to Sitecore.WFFM.Abstractions.Actions.ISaveAction

Please verify your code if your classes inherits from Sitecore.Form.Core.Submit.ISaveAction

You need to change your submit button to use new action. Please check here how to create a new save action:


  • The old form which i am using earlier, is there any way in which i can use that form or should i need to recreate the form with new save action? Feb 1, 2017 at 7:58
  • You need to change just the save action Feb 1, 2017 at 8:01
