One of our users recently noticed that pagination of a certain article does no longer work. This article shares a PageLayout with a CS containing some photos (more than one page). Pagination of the CS seems to be working fine. Selecting a different page for the Article asset, however, always leads to the first page. URLs are of type .../michas-reisetagebuch?pn-_Mg=<page_numer>. Interestingly, after turning administration mode on, pagination works as expected. After going back to normal mode the problem is there again.

Unfortunately there is no error in the log. I am 100% certain this used to work in the past. I can only suspect that fixing the recent pagination bug caused the problem. But I have not done any research yet.
