I have a clean install of 4.6.1 on Win2k3, IIS6, SQL 2005 and get the following when i try and create a new node:

As there is no specific place to look for this error i'm unsure how to solve it.
Thanks for your answer but i think i've sorted it out.
I created a Document Type called Home and gave it some tabs and generic properties. I then created another Document Type called Textpage and this was a child item of the Home type.
I added another control onto one of the tabs that i'd created in the Home type, this appears to be a new feature in 4.6.1, and i think it was adding this property that caused this problem as when i removed it this error went away.
Yes the inheritance stuff has gotten a makeover making it even more flexible and useable. Unfortunately it has been a bit buggy in version 4.6.1 - This is fixed in the coming v4.7 release though.
If it's a big issue for you it's possible to get the latest nightly build from nightly.umbraco.org and copy over the bin,install,umbraco and umbraco_client folder (remember to backup you installation first) and then if everything is succesfull you should be good to go.
Been reading through this thread as the company I work for are currently developing a blog using blog 4 umbraco on version 4.6.1. We're getting the same error on the creation of new blog posts, but only on the first (and sometimes second) attempts....then it tends to work ok.
Would downloading the latest folders from nightly.umbraco.org correct this error? If so would we have to get the folders from 4.6.2beta or 4.7?

Any ideas how to solve this?

Hi Chris
Is it when you click on the "create" button this error happens or is it when you have chosen what document type you want to add?

I have done it on a minor installation of mine.

Actually dont worry, we've just solved it by turning off pingServices as suggested on this thread
