I am upgrading the site from CMS 5 R2 to CMS 6. Upgradition was done with some hickups :)

but after upgradation site is compiling sucessfully but when we run the site we get this error "multiple custom attributes of the same type found". It is pointing to the temporary internet files. We cleared the folder but are still facing the same issue.

Any one know what this issue is and how to solve it.

Could it be something similar to this error? http://forums.asp.net/p/980517/3809849.aspx Many articles out there about this, several reasons for the error apparently.
