We updated version 6.15.6 to 7.3.2 or today again to 7.3.5 (to avoid errors) and since then we can no longer edit old pages. Creating new pages, changing and also deleting is easy. If you want to edit an old page you get the German message:
Bearbeiten nicht möglich
Bearbeiten ist momentan nicht verfügbar. Versuchen Sie es in wenigen Minuten erneut.
I have checked all sorts of settings etc. and according to Confluence the system is also working properly - i.e. all system check settings are green and ok. It's not because of the iptables proxy either. I have already deactivated Iptables and changed the port to 8090 directly or tested without success - same problem
We urgently need a solution because we can no longer adapt old pages.
