I have to bring issue 2849 up again. After changing the visibility of my collection from "friends" to "public" and back to "friends", the author's pages were filled with entries.
But after several hours, the pages were empty again (after reindexing?) and I had to change the visibility of my entire collection back to "public" or "private" to fill the author's pages again with entries.
Is there any limiation in the visibility of "other -> friends"?
