Unable to load html helper mode--error
I checked the pieced of code you published
You should write
(cons '("\\.html$" . html-helper-mode) auto-mode-alist))
(setq auto-mode-alist (cons '("\.html$" . html-helper-mode)
but that's not a problem that can cause your error.
Maybe the error is somewere else...
For problems specific to hth, please feel free to contact me.
