It is quite likely an issue due to changes in cider. Cider from melpa
gets a lot of updates and is a fast moving target.

IMO cider is not the best back end to use with org. You are probably
better off using inf-clojure. The cider back end has a lot of complexity
to support repl driven development which really complicates matters when
your just wanting to get clojure blocks evaluated and results back. The
inf-clojure back end is much simpler and undergoes less change, so is
more stable.

Personally, I'm not using this functionality in org. I found the
complexities of trying to get clojure blocks to work in this way was way
too high once you tried to do anything more than very simple statement
evaluation. I now use a more traditional literate programming approach
where I maintain the code in org files, but tangle the whole file to get
a clj/cljs file, which is what is loaded into the repl.
