I'm hoping someone out there can help.

I'm using the Community edition 05.02.03. I have created several different portals and assigned aliases to each. Everything has been operating smoothly for a few months now. I was updating each portal as recent as last night. This morning, all the portals are down. My host did a trace and came up with this error:

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

 

[NullReferenceException: Object reference not set to an instance of an object.]

   DotNetNuke.Entities.Portals.PortalSettings..ctor(Int32 tabID, PortalAliasInfo objPortalAliasInfo) +48

   DotNetNuke.HttpModules.UrlRewriteModule.OnBeginRequest(Object s, EventArgs e) +2988

   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +68

   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

The fact that I can't even access any of the portals is an bovious problem. I'm stuck. Can anyone help?

Jim

It appears that the site was upgraded from 05.02.03 to the newly released 05.06.00 which does have a known issue resulting in the generation of the same error you are receiving.

You may be able to access the site by appending /Default.aspx to the end of the hostname in the url - i.e. www.example.com/Default.aspx.
My recommendation for now would be to restore the site back to 05.02.03 using the file system and database backups that either you or the host hopefully created prior to the upgrade. You might then consider upgrading to 05.05.01.

A couple of questions for you to help us track down the causes of this issue:

1. Have you created any custom .aspx pages outside of DotNetNuke?
2. Are image file types being mapped (in IIS settings) to ASP.Net?
3. If using IIS 7 or 7.5, was the attribute runAllManagedModulesForAllRequests="true" added to the <modules> node of the <system.webServer> section of the installation's web.config file?
4. Please check the PortalAlias table in the database or if you can log in as host check the Admin-->Site Settings page to see if all of your portal aliases are still correct or if others have been added.

Hi William,

1. Have you created any custom .aspx pages outside of DotNetNuke?
No
2. Are image file types being mapped (in IIS settings) to ASP.Net?
No sure
3. If using IIS 7 or 7.5, was the attribute runAllManagedModulesForAllRequests="true" added to the <modules> node of the <system.webServer> section of the installation's web.config file?
No - there was no attribute like the one you list above in the we.config file
4. Please check the PortalAlias table in the database or if you can log in as host check the Admin-->Site Settings page to see if all of your portal aliases are still correct or if others have been added.
None of the portals open at all, so I can't log in. The aliases are correct in the database.

What now??

Jim

Also William I forgot to mention that we never upgraded to 05.06.00. I downloaded 05.05.01. Perhaps I should do the upgrade and see what happens?

So you were updating from 5.2.3 to 5.6.0 when this happened?

check your web.config for this line:

<system.webserver>
<modules runAllManagedModulesForAllRequests="true">

change it to

<system.webserver>
<modules>

Save the web.config and restart IIS and rehit the site

We know ActiveSocial module creates the above line it may also be added by other modules.

Also, have you mapped any files via IIS? Specifically PNG image files?
Doing so will also cause your site to fail after upgrade.

Gemini issues for your reference:


DNN-14455 - YSOD if upgrade web.config contains modules runAllManagedModulesForAllRequests="true"

DNN-14451 - Mutliple portal alias links created if you map PNG files to ASP.NET
