undefined method `open' for #<ActiveRecord::Relation [#<WikiPage id: 465>]>]

Hi,

I can't browse wiki pages when redmine_tags is installed. I have pulled the latest master today with the same result:

It's the same for all wiki pages.

I have the same problem with Redmine 3.2.

I solved it by commenting out the following line in file wiki_page_patch.rb

      # ids_scope = ids_scope.open if options[:open_only]

@sergeyb49 indeed that is the fix. Would you like to submit a PR removing that line and the documentation for the 'open_only' option above?

This is now fixed on master
