Hello, I have Plesk 9.3 installed on Windows 2008 R2 64bit. I have recently put FileManager on a website and when I try and use it to browse to a directory I get the following error: ============================================================================ Server Error in '/' Application. Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: Could not load file or assembly 'System.ServiceModel, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. Access is denied.

Since it's reported from an XML file in side the runtime rather than a file in our products I would guess this is a server installation issue. Try re-installing the .NET framework? ============================================================================ Is there anyway I can test or troubleshoot this error via Plesk?
