(crap, could not edit original post)

Hi, 2 problems emerged after updating a (local) site to 4.11:

In the backoffice I get the following error after clicking on a node in the content tree:

Value cannot be null.Parameter name: umbracoContext

Stack trace:
[ArgumentNullException: Value cannot be null.Parameter name: umbracoContext]   Umbraco.Web.UmbracoHelper..ctor(UmbracoContext umbracoContext) +134   umbraco.library.ReplaceLineBreaks(String text) +44   umbraco.controls.ContentControl.addControlNew(Property p, TabPage tp, String Caption) +2353   umbraco.controls.ContentControl.CreateChildControls() +1772   System.Web.UI.Control.EnsureChildControls() +189   umbraco.controls.ContentControl.OnInit(EventArgs e) +51   System.Web.UI.Control.InitRecursive(Control namingContainer) +186   System.Web.UI.Control.AddedControl(Control control, Int32 index) +189   umbraco.cms.presentation.editContent.OnInit(EventArgs e) +1007   System.Web.UI.Control.InitRecursive(Control namingContainer) +186   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +

At te site itself (on every page):
Object reference not set to an instance of an object

Stack trace:
[NullReferenceException: Object reference not set to an instance of an object.]   umbraco.UmbracoDefault.OnPreInit(EventArgs e) +202   System.Web.UI.Page.PerformPreInit() +48   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1843

Any help appreciated.

Just done this very update and dont have that issue, but i have very few packages installed, could it be related to packages you have installed?

Although i should point out i went from 4.10.1 to 4.11

S

what version did u upgrade from ? 

I came form 4.9

Is System.Web.Mvc.dll in the /bin folder?

Yes, it is. I've also tried to remove it. Didn't help

Which version of the MVC-dll do you have in the /bin?

The 3.0 version

Can u try compare global.asax from u solution with the one found in 4.11 zipfile

Troels,

I didn't have one so I just copied over the one from the zip

and now it is running like a charm ? 

No, the problem remains after the copy action

Ok, it finally works again. I've compared the default 4.11 web.config with the one from the site and appareantly had some difference between them.

All is good now. Thanks for all the suggestions.

Hi Vincent, what exactly was the problem with web.config?

I seem to have the exact same exceptions after upgrading.

Thanks in advance!

Michiel,

I basicly tried to run a 4.11 site with a 4.9 web.config. I solved it by comparing the web.config with the one supplied in the 4.11 download.

Okay. In my case it was the new Umbraco HTTP Module that I added to <system.webServer> but not to <system.web>

is working on a reply...
