Thanks Francis, so like this? If so I still have no luck 404.
@panel_files {
path /panel
file {
try_files {path} /index.php
}
}
rewrite @panel_files {http.matchers.file.relative}
I did remove this, cleared my browser cache and tried running without, but it dos not work. The previous version of Caddy v1 did of course work and required it.
