I have activated APCu and tried different PHP versions 7.4 to 8.1 but I always get the error in WordPress that I should use a persistant object cache with the Performance Lab plugin.

Thanks for helping test the Performance Lab plugin @pat2021 !

Have you installed a corresponding APCu plugin so WordPress can talk to APCu? If not then that's likely the issue.

If that's not the problem, please post a new thread on the Performance Lab plugin forum at
