When I try to log in to the CMS i get the following error and the only way to resolve this is to do an IIS reset. This happens almost on a daily basis now any help would be greatly appreciated.

Darren,

Do you have the website in its own app pool?  Are your permissions all correct and do you have any action handlers setup?

Regards

Ismail

Hi Ismail,

The website has it's own app pool and no action handlers have been setup as far as i can see permissions are all correct unless I am missing something. Thanks for your speedy response.

Regards

Darren

Darren,

What version of umbraco / IIS and windows are you using?

Regards

Ismail 

Ismail,

umbraco v 4.0.3 (Assembly version: 1.0.3625.27276)

Windows Server 2003 R2 sp 2

IIS 6.0

Regards

Darren

Darren,

The only time i have seen errors like this are when permissions have not been setup properly on umbraco install directories and when site is not in its own app pool we have already tested those bits.  

The only other thing to check is do you have any custom datatypes installed it may be one of those is causing the issue? although that usually manifests itself with yellow screen of death when you try to open a document using that datatype.

One more thing can you also check the latest entries in the database umbracolog table is there anything in there to give us a clue?

Regards

Ismail

Ismail,

These seem to be the only things that stand out in the umbracolog table and correspond with the CMS displaying the error

Darren,

Looking at the stack trace

The type initializer for 'umbraco.BusinessLogic.Actions.Action' threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object

it looks like an action handler is causing the issue can you trying installing the package http://our.umbraco.org/projects/event-viewer and see what action handlers you have setup

Regards

Ismail

I'd take a guess that you have an action handler which is configured in your site but it's missing a reference to an external DLL.

Have you got any packages installed on the site?

Ismail,

After installing the event viewer package this was the return that i recieved.

ActionHandlers

umbraco.cms.businesslogic.web.DomainDeleteHandler => cms.DLL
umbraco.ActionHandlers.umbEnsureUniqueName => umbraco.DLL

Events

umbraco.cms.businesslogic.web.Access

AfterRemoveProtection

Method: Access_AfterRemoveProtection => umbraco.DLL
(Namespace: umbraco.presentation.nodeFactory.UmbracoSiteMapProviderAccessUpdate)

AfterAddMemberShipRoleToDocument

Method: Access_AfterAddMemberShipRoleToDocument => umbraco.DLL
(Namespace: umbraco.presentation.nodeFactory.UmbracoSiteMapProviderAccessUpdate)

AfterRemoveMemberShipRoleToDocument

Method: Access_AfterRemoveMemberShipRoleToDocument => umbraco.DLL
(Namespace: umbraco.presentation.nodeFactory.UmbracoSiteMapProviderAccessUpdate)

 

Slace,

I have not installed any packages so anything that is there must have been standard.

Regards

Darren

Hi Darren,

have you resolved this problem?

I'm experiencing the same with one of my sites.

It doesn't have action handlers per se, but some packages and a costum data type. But I cannot see that anything is missing.

But this is also a 4.0.3 installation, and this particular version seems a little unstable to me.

May be an upgrade is the solution?

 

Siw

Hi Siw,

No resolution to this problem was ever found I was in contact with Umbraco Support regarding this but they wanted me to update to the latest stable version.

I personally have not upgraded as yet due to other projects but it is in the pipeline. Fingers crossed that will resolve the issue.

Darren

Personally I believe upgrading will help, as I said the v. 4.0.3 seems not so stable.

Unfortunately I have several sites on that version, but only 2 large sites - one of them being the one I have to refresh the app pool for, on a regular basis.

I don't look forward to upgrading xslt schema, checking which packages will work on next version, and so on, but I think it's necessary. Do you go for v. 4.7?

Fingers crossed for you, and please inform me if this does the trick :-)

Siw

is working on a reply...
