Document Libraries error

Hello dear Telerik team.

Some time ago I met the issue after update to version 7.0 : Image Libraries stopped to work. I resolved it using the method proposed by your team here:

www.sitefinity.com/.../error-when-going-to-content-images-after-6-1-upgrade

Now the similar issue appeared for Documents: when I try to access any subfolder in Documents list - I get the error:

Message : Object reference not set to an instance of an object.

Reinstallation of Libraries module doesn't fix it, and other Libraries work correctly. I use version 7.1 and all other features seem to work too. Could you please give me any advice?

Hello Serge,

The solution provided in the other thread is related to a problem that is similar to the one that you are currently experiencing, but I am not hundred percent sure why it is not working for your project. My advise is to open a support ticket where you can send us a copy of your project and database. Using this approach we can debug your project against the source code of Sitefinity and then suggest how this problem can be fixed.
