I tried to find reason for this error on the web, but there is nothing about that. I have installed DNN 6.0.0 and decide to upgrade it to 6.0.1 but the error is still there. Then I noticed that I have Recent blog entries modules displayed on my Home page. I added it few days before using Modules menu from admin menu. I didn't tried to remove it from the Home page and than to add it to a Blog page using Add blog module part. Maybe it will work this way but I didn't tested it. Instead I tried to add Recent blog entries blog module part to a Blog page in the same way how I added it to the Home page and it works.

So if you get same error maybe you have this module displayed on some other pages. To add it to a new page click Modules in the admin menu. Select Add Existing Module and under the Page select the page which contain it, and then add it to the page. Like on the image bellow:
