A Site of mine has a strange behavior.
From time to time some of pages are unpublished without any userinteraction.
In page history is no entry about any activity.
The involved pages are children of an secured subpage.

The unpublished Pages are not always the same. It varied in what page and in the period.
The apache access files give no information about any access from the outside.

For testing i have changed the content of these pages.
After waiting for some Days theses page is unpublished again. The content instead was not touched.
So I can exclude the possibility of an nightliy recover of the database by the provider.

How can this by possible. Any ideas?

System: 3.1.12 (CMS/Framework)
