Hi,

I thought I'd give it a try here as well. The problem appears when trying to make a simple password protection, see below.

umbraco v 4.0.0 / MySQL 5.0.67 / Windows XP Pro / IIS 5.1

---------------------------------------------------------------------------

"Login" template created and macro inserted as below:

Code:
<umbraco:Macro LogOutOnly="0" LoggedInText="test" SignOutLinkText="test2" macroAlias="MemberLogin" Alias="MemberLogin" runat="server"></umbraco:Macro>

</div> </div>

within form tags.

Text type document called "Login" created with "Login" above as template.

Now if preview the "Login" document, the login form appears, which, I guess means that the macro is used correctly, BUT

when I right-click on a node, choose Public Access, Single user protection, I get an error when I press Update after entering login and pass, and giving "Login" page as both login and error page.

The error I get is the following:

Code:
Server Error in '/' Application.

No node exists with id '0'
