Error: A copy of ApplicationHelper has been removed from

Rails
1

Hello.

I just started getting this error but can’t figure out what I did in the
past day that might be causing this:
“A copy of ApplicationHelper has been removed from the module tree but
is still active!”

Apparently, there are others that have seen this – gathering from a
google search – but I can’t find any solution.

Has anyone seen this? Here is what I’ve done recently:

  1. Added ssl plugin
  2. Added a couple authorize.net ruby code to my lib/ dir:
    http://developer.authorize.net/samplecode/

Thanks.
