I am receiving this error when trying to setup a new textbox or edit an existing texbox in all themes including the standard theme with BE 1.6.  This is with a new setup using my updated Vista Database which is working fine.

I also tried this a new setup using the default xml and the standard theme, same error message.

Thanks you for your help.

I tested with BE 1.6 and couldn't reproduce  :(

I don't think the storage location matters (DB, XML), as you noticed.

In the WidgetEditor.aspx page in the ADMIN folder, does the top line include ValidateRequest="false" ?

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="WidgetEditor.aspx.cs" Inherits="User_controls_WidgetEditor" ValidateRequest="false" %>

The ValidateRequest part was even in prior versions too.  So I'm guessing you probably have that part.

Sorry, right now that's all that's coming to mind .....

Yes, I checked the WidgetEditor.aspx, it is as above.

Not sure what to try next.

Well I rebooted my computer, and also changed the build from 4.0 back down to 2.0 and the issue has been resolved.

I think I will change the build to 3.0 and check it, and then 3.5 and then back to 4 and see what happens.

Mystery solved, it works fine with build 3.5 but does not work with 4.0.
