Tridion UI 2012 - Error "The item tcm:280-29837-64 does not exist."

Question

When we are trying to create a new page through a PageType in Tridion UI.It is throwing below error --

"The item tcm:280-29837-64 does not exist."

Is it the Id of the page which i want to create,as it is no more exists in the tridion?

Could any body help me out in this regard ?

Note :-we defined the pagetype to those pages which already exist and published.

Edit-1 When we click on the 'Create Page' button(see the attached screenshot), above mentioned error Pops up.

In the cd_core.log file below error and warning comes --

ERROR XMLConfigurationReader - Error while validating file 'cd_ambient_conf.xml' with schema 'schemas/cd_ambient_conf.xsd'. cvc-complex-type.2.4.a: Invalid content was found starting with element 'ClaimStoreProvider'. One of '{Cookies}' is expected.

WARN AmbientDataContext - There is no current ambient data context - the ambient data framework is not properly initialised

Edit-2 Now errors related to AmbientDataWork are resolved but we are still getting same issue. There are two options in UI (a) "New Page" (b) Create and insert Content. This error also comes when we go with the option "Create and Insert Content". On each click of "Create Page" or "Create and insert Content" it generate a new Id(XXX-59248 -64 then XXX-59249- 64 etc) for page and same way for component also and throws above mentioned error message.

Note:- We are using IIS 6.

Edit-3 - I am using VB script in my page templates.

Answer 1

If someone is using VB script page template,it is required to install UI_2012.0.0.81248 hotfixes to create new pages in UI 2012. I was not aware about this so fact of using VB script is not mentioned anywhere in the question .So I am updating my question again to assist community member in right direction.
