The only change that I made between the backend working and not was adding some dlls into the bin. In that post, there is no clear resolution of the problem.
So is this known? Why does it happen? Is it *really* the case that this just happens from time to time and Umbraco users are expected to live with it?
Input on this would be greatly appreciated. Thanks.
Could you maybe give some info about which dll's you copied and which version of Umbraco you are using. I had a similar problem due to the fact that I was using the AjaxToolkit dll for .Net 3.5 while the backend was working with the version 2.0 dll.
Knowing what you actually added/overwrote in the bin might hlep identify the issue.
I had wanted to use the PerceptiveMCAPI (wrapper for the Mailchimp API: http://perceptivemcapi.codeplex.com/). It uses the dll CookComputing.XmlRpcV2, however that is also used in Umbraco. In putting that in the bin I had replaced the version that Umbraco came with. Rolling-back to Umbraco's version fixes my disappearing nodes, but then the PerceptiveMCAPI throws an exception since the version is wants is missing.
The version of CookComputing.XmlRpcV2.dll that comes with Umbraco is 2.2.04 while the version used by PerceptiveMCAPI I am using is 2.5.0.0.
So how can I use the PerceptiveMCAPI since a dll it wants to use is already in the bin with Umbraco but updating that dll breaks the Umbraco backend?
Backend nodes not loading
Hi,
I have a big problem with all the nodes in the various sections of the admin backend not loading. Similar to what is describe in this post:

Hi bob,
There are several ways of solving this I think. You might want to haver a look at this other discussion: http://our.umbraco.org/forum/developers/api-questions/20570-Use-different-versions-of-dlls
There are different solutions mentioned, you might want to have a look at them :
http://geekswithblogs.net/narent/archive/2008/11/11/126940.aspx (assemblies in different folders)

http://nerobrain.blogspot.com/2011/04/loading-different-versions-of-same-net.html (put different versions of an assembly in separate folders)
Hopefully one will fit your needs :-)

Hi Bob,
I just recompiled the latest Perceptive API to work with Umbraco 4.7. If you provide me your email, I'll send it over to you.
Hope this helps (please mark as answer if it's what you're looking for)

Actually, here's a link with the zipped dll. That way others can use it if they run into the same issue:
