Unfortunately, there is an issue in the DotNetNuke.Modules.Documents.dll file contained in all of the Documents 4.01.01 packages downloaded from CodePlex since 7 p.m. EST or so on March 9th. The acting project team lead is aware of this issue and will be taking steps to correct it as soon as possible. In the meanwhile, if you need to restore the functioning of the Documents module immediately, the DotNetNuke Community Edition 05.06.02 BETA packages available on CodePlex at
http://dotnetnuke.codeplex.com/releas...
contain a Documents 4.01.01 install package that is not affected by this issue. You would need to:
1. Download and extract the 05.06.02 BETA install package to a local folder.
2. In the extracted package's Install/Module folder find the file Documents_04.01.01_Install.resources.
3. Rename this file to Documents_04.01.01_Install.zip
4. Navigate to your site's the Host -->Extensions tab in DNN 5.x or the Host --> Module Definitions tab in DNN 4.9.5 and using the Install Extension or Install Module wizard install the Documents_04.01.01_Install.zip that you have obtained from the BETA package.
5. DNN will treat this as a repair installation replacing the bad assembly and other files but not running the SQL scripts.
Note in particular that the Documents package you obtain from the Community Edition 05.06.02 BETA package will be compatible with DotNetNuke versions 4.09.05 and later only and NOT with versions 4.06.02 and later. If this issue ocurred when installing the Documents 04.01.01 package obtained from Codeplex into a DotNetNuke version earlier than 4.09.05, you will either need to wait for the fixed package to become available on CodePlex.
