I have upgraded the Confluence version from 7.19.19 to 8.5.18 version. After upgrade few admin related pages are showing page not found. Admin pages like maintenance and few other pages as well. I couldn't make the application to read only while performing the admin related activities.
An upgrade that causes pages to vanish is quite strange.
The pages are kept in the database. Do you have database access to check if they are really gone?
Or did you change any database settings in the upgrade process?
Hi,we have same problem.Only changes what we did to database connection is to disable encryption.
Try start with safe-mode.After all apps are stopped restart apps one by one and check the functionality.We found correction by changing starting order of apps (manually).
Hi Vesa
Do you mean this issue was caused by a specific app?
