i did setup a multilingual page with babel where i have 2 other contexts beside web. There is a protected area for members in every context. When a non logged in user tries to load a member page of the web context the "not_authorized" system setting redirects to the specified resource, fine.
When i do the same in another context a 404 appears. I followd a post which says you can set for every context a "not_authorized" which did not worked. Then i followed "Unauthorized Versus Error Page" from http://bobsguides.com/revolution-permissions.html
but still the 404. Error logs says
[2015-05-22 14:00:28] (INFO @ /index.php) Principal 0 does not have permission to load object of class modDocument with primary key: 492
Cache and permissions flushed like 1000 times. I don't know what to check else. Im on revo 2.2.15
btw. when im adding screenshots, i just get redirected to an empty "new post" page
