    Object reference not set to an instance of an object.

    Using Contour v3.0.17 with Umbraco v6.1.6 and strangely today a production site was reporting "Object reference not set to an instance of an object." for all Contour forms on the front end and every dialog in the UI was also displaying YSOD. Example full error from log file below. An application pool recycle and all working fine again, not sure if it's something to worry about..?

    I have hit something similar when upgrading Contour from v3.0.6 to v3.0.17 on Umbraco v4.11.8. It has taken the whole site down. We have a lot of code first forms on this site.

    Thanks Tim, no it didn't want to come back at all until I restored the backup files. This is the dev site which is on Contour v3.0.6 but the live site is on v3.0.14 both on Umbraco 4.11.8. I want to upgrade to get round this issue: Using RecordService to delete record results in Exception1

    so I might just go up to v3.0.15 for now?

    correction, I will try v3.0.16 as 3.0.15 doesn't like Umbraco v4

    Ok, so I also get the error upgrading from v3.0.6 to v3.0.16. Everything is fine when I upgrade to v3.0.14 but this does not get me where I need to be. Upgrading to Umbraco v6 is not currently an option.

    Ok will try to reproduce, any chance you can try to deploy your forms to a fresh Umbraco instance with Contour just to see if that works?

    Great, thanks Tim. I created a fresh Umbraco v4.11.8 instance, added Contour v3.0.17 and dropped in my forms dll and I can see the forms on the dashboard fine and they display on a template ok (although there is no Contour tree or section icon - I think this might have been the Umbraco permissions were not set when I installed Contour)

    It might be worth mentioning that I also have the 'Could not load control: '/usercontrols/dashboards/ContactFormlogs.ascx' and 'EmailAFriendFormlogs.ascx' errors on the content dashboard - there's no starter kit installed so it must have come from Contour?

    Ok so it's sorted? No errors aren't from Contour sounds like something from a starter kit :)

    Thanks Tim, it's all sorted. On the strength of Contour working in a fresh install, I applied the upgrade to the live site and everything works perfectly. So sorry - there must be something up with the dev site!
