Using the latest helm and ergoemacs-mode from Melpa Stable on Emacs 25.1, I get an error when trying to open any files through C-o: 'void variable helm-follow-mode'. Example .emacs:
Adding (setq helm-follow-mode nil) as a workaround lets me open files again. I had the same problem with the old stable ergoemacs on Emacs 24.5 after upgrading helm a few days ago, so I suspect something has changed there.
