I have two identical InfoPath forms on two different site collections within the same web application (SP2010). One works fine but the other produces this error when submitting the form....
The form cannot be submitted. One or more field types are not installed properly. Go to the list settings page to delete these fields.
An entry has been added to the Windows event log of the server. Log ID:5567
I go to the list settings page but I have no idea which fields are not installed properly!
It opens in InfoPath and publishes without error.
I am a newbie to Sharepoint and the only references I can find when Googling talk about CAML queries and mismatching field names but I've no idea where to find CAML queries and fieldnames appear to be OK. I have played "spot the difference" with the working form and cannot find anything. All the fields are in a ContentType used by both forms.
The equivalent "edit" form works fine - again I can't see any significant difference with it.
Any clues would be most appreciated.
