"Page Not Found" error when clicking any link from the Page Tree

Question

I have a space where access is granted to any logged in user. However, when a user clicks on any link from the Page Tree, they get the "Page Not Found" error.

The issue does not happen with my system admin account. Moreover, if the user goes directly to the URL of the page they are trying to access, they don't get any error.

Our instance was upgraded yesterday to Confluence Server 8.5.4, and the issue appears to have started after the upgrade.

Thank you for any information you may provide.

QQ - Having the same issue on upgrading to 8.5.5 version.
Did rebuild the index. Wondering if anyone was able to get it resolved? 
Happening with only a few pages in one of the space. Hoping to not need to rebuild the whole.

Hi @Carlos Sánchez,

Looks like the issue might be related to the index. Have you rebuilt site index after the version upgrade? If not, please try to reindex your site or just the affected space.
