Fixing Babel in Org mode

Once in a while Emacs and/or Org mode throws me a curveball. Today’s example is that suddenly I couldn’t run anything using Org-babel. Trying to do so would result in something like…

evaluation of this R code block is disabled

I noticed the following error during startup…

Invalid function: org-babel-header-args-safe-fn

Based on a recommendation in this Github issue I ran spacemacs/recompile-elpa, relaunched Emacs, and all is well.
