Description
Issue Summary
The user upgraded Confluence 5.7.1 to v7.4.1 as suggested by official upgrade guide https://confluence.atlassian.com/doc/upgrading-confluence-manually-255363437.html
After the upgrade, there was `Failed to initialize evaluator cache` error in log. It's unclear if the issue is caused by upgrade or something else. The risk is that the cache is in a stale state and the user will see the wrong info on the Who Can View dialog.

Workaround
A possible workaround is to disable and re-enable the Gatekeeper add-on so that the cache can be re-initialized.
