Steps:

1. Log in
2. Go to Page
3. Create new landing page and publish it
4. Go to Dashboard
5. Click on your new LP to go to preview mode
6. Click on Page from top menu - LP is shown, but there is an error:

Cannot get page information from the server

Console shows:

GET http://eev2/studio/urlaliasinfo?url=%2Fsite%2Ftest&siteAccessName=site 404 (Not Found)

Unknown macro: {message}

undefined

It only works that way on prod. Dev mode works fine.
