Datastore Admin page: enabling page failed

[Dennis]

I'm having problems enabling the datastore admin page.

I tried to enable it yesterday and got a login error message.

After waiting a day (and logging out and back in) I still get this login error message:

Server error

Sorry, you've reached a login page for a domain that isn't using Google Apps. Please check the web address and try again. Learn more

There was a proposed fix by Greg Darke in this post:

https://groups.google.com/group/google-appengine/tree/browse_frm/thread/1def08a1142d3c63/a201f46143f60366?rnum=1&q=admin+enable&_done=%2Fgroup%2Fgoogle-appengine%2Fbrowse_frm%2Fthread%2F1def08a1142d3c63%3Ftvc%3D1%26q%3Dadmin%2Benable%26pli%3D1%26#doc_3f636d9501b02ae5 

but when I tried the url I get a 404 error.

What's the current fix for this bug??
