Server Error in '/' Application.

Access to the path 'DataTypeGrid' is denied.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.UnauthorizedAccessException: Access to the path 'DataTypeGrid' is denied. 

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. 

To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

I have the same problem with a fresh Umbraco 6.0 installation.

Hi guys, I'm looking into this today. Will let you know what I find.

Thanks, Lee.

OK, we found that v5.3.1 introduced a bug that breaks the Prevalue Editor - totally my fault (I made the last minute code change - sorry!)

We'll be putting out a patch release as soon as possible ... unless then, best option will be to downgrade to v5.3.0.

Thanks, Lee.

uComponents v5.3.2 fixed the issue. Thanks a lot.

is working on a reply...
