I'm getting the above error when trying to amend a field on a contour form. We can create a new form, but then trying to amend a field gives the error again.

We have 5 machines here, and this is happening on 4 of them. 1 machine is not affected.
Hi I would advise you to upgrade Contour, might be that this was a bug in the version you are using, upgrade instructions can be found on the project page http://our.umbraco.org/projects/umbraco-pro/contour
Since there are some schema changes between version 1 and 3 your db will also need to be updated, you can execute the upgrade script by requesting the page mysite.com/umbraco/plugins/umbracocontour/upgrade.aspx after requesting that page your schema will be updated and you'll have a new insert form macro in the developer section.
If that fails you can also run the sql manually, the scripts can be found on the source code tab below

Umbraco version: 4.9.1
Contour version: 1.1.10

If you don't want to go to version 3 at least go to 1.1.13.2
From what I can see in the history this bug was fixed for version 1.1.13.1 http://nightly.umbraco.org/Umbraco%20Contour/changes.txt
Thanks Tim.
Upgrading to version 3 from 1.1.10, is this just a case of uploading the files in the upgrade.zip package ? Are there any database updates ?
Detailed on the project page :)
Upgrading from 1.x to 3.x

So yes there are db changes (2 extra tables for the conditional logic stuff)
Thanks, I saw that but was confused by the v1.xx to 3.xx as I couldn't see any revision 2 !!
Will upgrade this afternoon.
version 2 was the one for Umbraco v5
is working on a reply...
