I upgrade my KooBoo site to version 3.1.0.38849.

I get error on edit content page if I navigate from new admin panel "Content Manager".

I try to show it on screens:

(Sample 1) This work fine If I click on some content folder from "Site manager" panel: (If I made only two clicks)

(Sample 2) This don't work If I click first on "Contents" menu (and go to panel "Content Manager") and then I do that two clicks from sample 1, I get the error when I click "Edit content".

I think it is URL problem with parameter - siteName=SampleSite.

Error text: "Exception Details: System.NullReferenceException: Object reference not set to an instance of an object."

Ok. I changed the image URL in first post. (It's difficult to understand the problem without them.)
This is error text:
[NullReferenceException: Object reference not set to an instance of an object.]

Oh, no, I use site only as admin (only one user). Can you see the pictures?

Yes, I have met the issue before, but I think it was fixed. I can not reproduce it now.

How did you upgrade the Koobo CMS? Can you download a fresh version to try if it works?

It is recommended to copy the Cms_Data to another Kooboo CMS folder.
