Hi Stefan,

What steps did you take to upgrade your Umbraco installation? Have you followed this instructions. http://our.umbraco.org/documentation/installation/upgrading/general

Download the .zip file for the new version you are upgrading to.

Copy the following folders from inside the .zip file over the existing folders in your site:

• /bin
• Only for versions lower than 7.1.0:
  • /Install (don't forget to remove it after the upgrade is finished)
  • This folder is no longer present or needed in Umbraco v7.1.0+
• /Umbraco
• /Umbraco_Client

And remember to compare the config files in the /Config and webconfig. To compare files you can use a tool like WinMerge

Is it possible for you to logon to the server to get more information about the error, or change the CustomErrors to Off in the Webconfig file, to get more information about it. If you do it, then remember to set it to RemoteOnly, when you have solved the issue.

Hope this helps,

/Dennis

I updated from 7.1.8 to 7.1.9 and did all the things which is required.

I have done it many times before.

Hi Stefan,

Okay have you tried to take a look in the log file folder (/App_Data/Logs) to see if this can give some information on is going wrong, Maybe this can help you further to find a soultion on how to fix this.

Hope this helps,

/Dennis

Hi Stefan

Besides checking the log could you please let us know what database you're running? Do you have any 3rd party packes that might be incompatible?

Have you tried clearing the TEMP files in /app_data/TEMP? Try clearing those and then increment the /config/ClientDependency.config files version attribute.

In Umbraco you should also try to rebuild the examine index, which can be done in the "Developer" section by clicking the "Developer" node then there should be an Examine Dashboard from, which it should be possible to rebuild the indexes.

Hope these pointers help.

It running on a MSSQL 2012 server. Cleared TEMP and rebuild the Index, also did the clietdependency increment.

Still i get the error.

This is the error in the log: 2014-11-28 12:11:20,287 [62] ERROR Umbraco.Core.UmbracoApplicationBase - [Thread 18] An unhandled exception occurred System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object. at umbraco.cms.presentation.create.controls.nodeType.PageLoad(Object sender, EventArgs e) at System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context) at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.umbracocreateaspx.ProcessRequest(HttpContext context) in c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\e0cdb9e9\35543385\AppWeb_create.aspx.5f2dec3.jefq3l4k.0.cs:line 0 at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Hi Stefan

Are you making use of some 3rd party packages with property editors that might not be working with Umbraco 7.1.9 for some reason?
