Did installing Umbraco Forms fix the issue? Sorry, just a bit confused about the edits about and want to make sure that you're not having problems anymore :)
Ok, good :) - Yeah...It's not ideal...I think that there should probably be some work done so it's not possible to install packages that are not compatible with the version of Umbraco one is using...but happy to hear you managed to figure everything out.

Hi Gerjan

Hi Jan, yes it did (uninstalled Contour and installed Forms).
My mistake! :) But I think the Umbraco Package Repository needs an update.
