.user.ini points auto_prepend_file to a missing file: HTTP 500 after a move
サイト所有者に見えていた症状
After the site was moved to another host, every page including the login page returned HTTP 500. The host error log showed "PHP Fatal error: Failed opening required '.../wordfence-waf.php'". A plain file (/license.txt) still returned 200.

補足
On this setup PHP-FPM re-reads .user.ini on a cache interval, so a change to that file takes effect after a delay rather than on the next request.
