Internal server error on page properties report macro

Question

Hello

Since we updated confluence server edition from 6.13.11 to 7.4.6 some pages display a system error.

The ones suffering from this all load the Page properties report macro. Not all pages using this macro display the error though.

The strange thing is, when opening the page as administrator, it does load perfectly. Other users can then visit the page temporarily as well.

What can be a cause of this and are there solutions?

We tried rebuilding from scratch several times, without success.

Copying the page with subpages to a personal space and copying them back afterwards solved it temporarily. Now after some time, the error reappears on certain pages.

You can do a reindex in the UI from this guide: Content Index Administration or rebuild the content indexes from scratch as described in How to Rebuild the Content Indexes From Scratch on Confluence Server.   Looking at others that have had this issue rebuilding from scratch is what resolved the issue permanently.   I would recommend giving that a try.
