@accessd I've the same problem. You managed to solve the problem.

@wagnerjgoncalves I use this fix accessd@a6078f2

[Wagner Gonçalves]

@accessd I'll see your fix, thanks.

The fix from @accessd also works for me using Rails 4.2.1 and Rails Email Preview 0.2.20

@scottharvey Why are you using 0.2.20 and not 0.2.29? I can merge a PR with the fix, though I have never been able to reproduce this error myself.

@glebm I looked into this further and in my case it was because I had moved the route inside the :admin namespace like this:

namespace :admin do
  mount RailsEmailPreview::Engine, at: 'emails'
end

Instead of keeping it at the top of the routes file and names spacing it like this

mount RailsEmailPreview::Engine, at: 'admin/emails'

This seems to be working now, thanks for the reply 😄
