New Install; no install errors; working great. Attempted to update the Admin Site Settings and received an error. Went back and attempted to select 'Update' without changing anything and still received the error below: Error: Site Settings is currently unavailable.

Goto Admin > Site Settings > Advanced Settings > Other Settings, and Check the Default Language is NOT Null or Selected as English (United States).

That did it!
Thanks,

If there is no language option in the dropdown menu, you can follow this link and run the suggested script to resolve the Language null issue: http://support.dotnetnuke.com/issue...x?id=10707

It worked for me on a new install of 5.1.2!

Workaround:

1.Go to the Admin/Languages page
2.Click on the Edit Languages link in the upper left corner of the module
3.Select a language from the Dropdown list.
4.Check the enabled checkbox
5.Click the update button.


Which is at the bottom of the http://support.dotnetnuke.com/issue...x?id=10707 page that Jason posted. I did this and it worked to get rid of my admin settings page error.

Unbelievably, when I go to Edit Languages in Admin/Languages, there is no dropdown of languages. Only Language label as well as Fallback Language label is shown. No dropdowns. Only Enabled checkbox is shown there. Whats the problem behind this ?

Step 1:

"go to Admin :: languages, and add "English (United States)". Make sure, it is enabled for your portal. you now may set it to be default language in site settings and in your user profile. subsequently, you are able to disable any other language."

If that doesn't work ...

Step 2:

Follow the instructions in Peter Donker's blog here.

Thanks Joe Craig. The query in step 2 ran fine. But the problem still exits.
I wanted to say that no dropdown is VISIBLE in the Edit Language page. So how can I select "English (United States)" as default language? Empty dropdown is another thing, at least you can see DROPDOWN on the page either empty or filled. But there is no Dropdown visible on the page .... why is this happening ?

OK.  Are you using a standard DotNetNuke skin, or are you using a custom or purchased skin?

I am using Standard DotNetNuke skin.

Well the problem has been resolved. Now "English(United States)" is visible in the dropdown.
However I did nothing special to resolve it. After running the step 2, I closed the Explorer and hence removed all sessions. After getting logged in, When I visited the Admin -> Languages page, I found "English(United States)" there in the dropdown.
Thanks for help ...
