has clojure refactor been removed from spacemacs clojure layer?

yes

would clj-refactor still be recommended or was it removed for good reason?

it is optional now, see the readme on how to enable it for your config: https://github.com/syl20bnr/spacemacs/blob/develop/layers/+lang/clojure/README.org#enabling-sayid-or-clj-refactor

(sorry, if my “yes” before was somehow misleading)

ah, should have read the docs 🙂

well, it could be easier to find online…

tern-find-definition is giving me a Request failed: ((wrong-type-argument stringp nil))` I tried debugging that, but my elisp skills aren't that great. I see that my tern-at-interesting--expression never returns anything, but even using tern-find-definition-by-name (where you type in the var you want) fails. Stepping in a bit I could see that on tern-req host is left as nil (instead of localhost?) and the url requests to the tern server fail. Is that the case for everyone?
