    我能够解决这个问题 . 我重新安装了WFFM 8.1的更新包 . 但在此之前，我将WFFM 8.1-Initial版本的DLL和配置文件复制并粘贴到我的实例中，然后再进行更新运行 .

    Edited ：根本原因，忘了用下面的补丁更新 Sitecore.Forms.config ：

    <handler type="Sitecore.Form.Core.WffmActionHandler, Sitecore.Forms.Core" method="OnWffmActionEventFired" > 
<param name="actionManager" ref="/sitecore/wffm/wffmActionExecutor" /> </handler>

    在我的情况下，我通过从clean-sitecore安装文件夹复制整个DLL修复，当更多挖掘它是谁是黑羊他们是

    • Sitecore.Forms.Core.dll

    • Sitecore.Forms.Custom.dll

    • Sitecore.Forms.Mvc.dll

    以上dll的版本不同 .
