A duplicate name "Item" was found

Hello,

I'm building a SharePoint 2007 site since 2 or 3 months or so. Now, all of
the sudden, when I try to create a new site collection of type "Collaboration
Portal" (publishing site), I get the following error (+ call stack):

Portal provisioning handler callout failed. Exception:
Microsoft.SharePoint.SPException: Provisioning did not succeed. Details: The
site template was not provisioned successfully. Delete this site collection
in Central Administration, and then create a new site collection.
OriginalException: Provisioning did not succeed. Details: Failed to create
the 'Cache Profiles' list. OriginalException: A duplicate name "Item" was
found. ---> Microsoft.SharePoint.SPException: Provisioning did not succeed.
Details: Failed to create the 'Cache Profiles' list.

(I have more if you want...)

Anyone have any idea how this can suddenly happen? I haven't found any
threads about this problem on the forums, and googling only gave me 2 or 3
results with other people having this problem, but never a solution... As you
can imagine this is a big problem because I can't seem to enable Publishing
anymore! (the same problem appears when activating the Publishing
Infrastructure feature)

Any comments are welcome!

OK... I managed to solve this problem!

OK... I managed to solve this problem! It has cost me a few hours but I'm
glad to have it working again.

When I looked at the site content types on an existing site, I noticed that
a lot of default content types (like tasks, announcements, etc) were just not
in the list. Only "Item", "Document" and all content types deriving from
that derives from "Item"). So I thought: maybe something's wrong with the
content types. So deactivating and activating the CTYPES feature was my next
option... no luck :(. Then I remembered that I had just added some content
types in a feature. I noticed that, in the ContentTypeID, I forgot to add two
zero's (00) to the parent ContentTypeID before adding my own GUID. I couldn't
deactivate my ContentTypes feature anymore (it threw an exception saying it
couldn't find the parent contenttype), so I edited my contenttypes.xml file
directly in the 12\TEMPLATE\FEATURES directory and added the necessary 00's.
Then I did an IISRESET and voila, my default content types were back and I
was again able to create Publishing sites!

Hope this helps someone!

A duplicate name "Item" was found while deploying content

Hi Sven,



I get similar exception while deploying content from source to destination. Any help would be highly appreciated.
