Asking because I doubt that it's a Fedora bug, but yous all are so knowledgable I'm sure someone can point me in the right direction.

I think there's a bug in php (fpm) for the Apache webserver. Unsetting the user_dir directive (& therefore I assume any similar directive) by resetting it to its initial state ("user_dir =", ie no value), does *not* unset the previous non-empty value.

Surely such a basic thing can't have been overlooked, and therefore I must've done something (else) wrong?

If not, where do I report that?

Many thanks.
