wrong number of arguments (0 for 1) on %= render_breadcrumbs. about breadcrumbs_on_rails

[johnkoht]

Are you using another plugin or engine that might use breadcrumbs? I tried using this plugin with Spree because I didn't want to use their built-in breadcrumbs and got the same errors. This method https://github.com/weppos/breadcrumbs_on_rails/blob/master/lib/breadcrumbs_on_rails/action_controller.rb#L26-L28 conflicted with a spree method and caused my error.

I ended up forking and renaming the method https://github.com/johnkoht/breadcrumbs_on_rails

same issue

ruby '2.0.0'
gem 'rails', '~> 4.1.0'

render_breadcrumbs is not willing to take any arguments

@johnkoht 's version produces same error in my case

I've got the inverse issue :
= render_breadcrumbs tag: "li"
wrong number of arguments (1 for 0)

The same issue. wrong number of arguments (1 for 0) But i fixed it. The reason is gems conflict.
In my case:

gem `twitter-bootstrap3-rails` 
# conflict with 
gem 'breadcrumbs_on_rails'.

When i removed gem twitter-bootstrap3-rails. The error went!
