INTRODUCTION

I have just upgraded a client’s website from Sitecore 8.0 to 8.2 Update 4. Then I also installed Web Forms for Marketers WFFM 8.2 Update 4. After the WFFM install somehow the Indexing Manager and Rebuild Link Databases link did not work. It returned 404.

The exact error message was:

Could not load type ‘Sitecore.Web.UI.Controls.SheerUI’

RESOLUTION

After some investigation I found out that the SheerUI.aspx page which is located in:

\Website\sitecore\shell\client\Business Component Library\Layouts\Renderings\Common\SheerUI

was updated to:

<%@ Page Language=”C#” AutoEventWireup=”true” CodeBehind=”SheerUI.aspx.cs” Inherits=”Sitecore.Web.UI.Controls.SheerUI” %>

Therefore, what I did was I unzip the original Sitecore 8.2 Update 4 files and open the same file. The correct one should be the following:

<%@ Page Language=”C#” AutoEventWireup=”true” Inherits=”Sitecore.Web.UI.Controls.Common.SheerUI.SheerUI” %>

Voila…it all worked fine again.

Hope this helps,

Tommy
