System.NullReferenceException on EditTree.aspx

There is something seriously wrong with the language settings on this site, perhaps to many developers has been involved.
When entering edit mode I get this YSoD where the pagetreestructure is supposed to be, I also get this message when entering "set access rights" in admin mode.

Globalization is NOT checked and page view is set to english.

What am I missing?

Best Regards
Sandra

I would check if the solution has extended the EditTree in anyway own icons, hiding pages for users and so on.

Thanks for your reply!
No nothing like that, no hiding pages or own icons or anything like it.

I got same problem yesterday. It is on e-Commerce site. I added two addition languages in e-Commerce and it starts fail. I found that it is customer pageprovider for e-Commerce which course the problem. After I disabled the pageprovider it works and I didn't investigate it more. Do you have any pageprovider?

EPiServer CMS 6 R2 with Commerce. Looking at episerver.config I find this

   <pageProvider>
        <providers>
            <add capabilities="MultiLanguage" entryPoint="64" name="CatalogPageProvider"
                type="EPiServer.Business.Commerce.Providers.CatalogPageProvider, EPiServer.Business.Commerce" />
        </providers>
    </pageProvider>

Has this anything to do with it?

Well the mystic like was:

 EPiServer.Core.PageProviderBase.SelectLanguageBranch(PageData page, ILanguageSelector selector) +102

Because when you look at the sdk the EPiServer.Core.PageProviderBase doesn't have a SelectLanguageBranch method on it. So was just guessing that the solution would have exted it.

I see that the course payed of Ruwen! Good catch!

that method is private and it is there in reflector. Could be a bug Commerce module.

I'm building a commerce site for a norwegian customer and had the exact same problem. I enabled a new language (norsk, nynorsk nn-NO) on the commerce side and create catalogs in that language. I found that if the newly enabled language don't have the same language enabled on the CMS side it crashes. I had norwegian (just "no") enabled on the CMS side and it crashed, however but when I enabled "nn-NO" everything worked fine again.
