Hmm can't really see what's going on from the stacktrace let me know if this happens again but for now this is the only case I have ever seen...

I had to degrade controur from 3.0.17 to 3.0.14 to make it work locally. Now I got the same problem when I try to upgarde from 3.0.14 to 3.0.19

Server Error in '/' Application.

I've got a simular issue when I try to upgrade contour from version 3.0.6 to 3.0.17 on localhost. This is an umbraco version 4.11.3.

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.

Also working fine after app pool restart?

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!

Ok great :)

is working on a reply...
