Question

有人运行了解以下问题吗？基本上，我正在尝试将营销人员的 Web 表单从 8.0-U3 升级到 8.0-U4（成功）到 8.1-初始版本（不成功）。

错误发生在更新安装过程中： http://upgrade/sitecore/admin/UpdateInstallationWizard.aspx

Answer 1

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，然后再进行运行更新。

已编辑：根本原因，忘记使用以下补丁更新 Sitecore.Forms.config：

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

Answer 2

在我的例子中，我已经通过从 clean-sitecore 安装文件夹复制整个 DLL 来修复，当更多挖掘它时，谁是黑羊在下面他们是

Sitecore.Forms.Core.dll
Sitecore.Forms.Custom.dll
Sitecore.Forms.Mvc.dll

以上dll版本不同
