I can't edit newly created Cloud portal site.

I got some trouble with Cloud portal Site.

I created new portal site for testing purpose yesterday,

and there was no problem to change some of the settings.

After a day passed, I just can't edit the site that I have created yesterday,

also can't edit any newly created sites.

If you have any clue, give me some. Thanks for your time.

*Sorry about the ambiguity about 'can't edit'.

When I push the EDIT button from Admin Space, another browser is opened with some kind of warning picture, so I can do nothing.
