Error while clicking on the Root Page and Recylce bin page in EPi Server Edit Mode


Hi Folks.

I am getting the following error while clicking the Root Page and Recycle Bin Page in the EPiServer Edit mode.

Parser Error Message: Unknown server tag 'EPiServerUI:SystemPrefix'.
Source Error:

Line 26:         <form id="aspnetForm" runat="server"> Line 27:             <asp:ContentPlaceHolder ID="FullRegion" runat="server"> Line 28:                 <EPiServerUI:SystemPrefix id="SystemPrefixControl" runat="server" /><br /><br /> Line 29:                 <asp:ValidationSummary ID="ValidationSummary" runat="server" CssClass="EP-validationSummary" ForeColor="Black" /> Line 30: 

Source File: /Marketing/UI/MasterPages/EPiServerUI.Master    Line: 28

How to fix this issue. It's very urgent.

Have you checked the page type settings for SysRoot and SysRecycleBin? Check the file name and see if it has the correct search path.
