Error when generating a PDF of an article with pictures

[Atmis]

Hello,

I get the following error when I try to generate a PDF and pictures are included in the article :

Completed 500 Internal Server Error in 500ms (ActiveRecord: 15.6ms)

NoMethodError (undefined method 'number_to_human_size' for #ArticlesController:0x0000000c964810):
lib/redmine/sudo_mode.rb:63:in 'sudo_mode'

Redmine is running on a Windows platform :

I just ran across the same problem, running Redmine 3.1 and the latest code from redmine_knowledgebase master branch. This might not be the best approach, but including NumberHelper worked for me. Here's the patch:

diff --git a/app/helpers/knowledgebase_helper.rb b/app/helpers/knowledgebase_helper.rb
index e24b1c1..3d7cf31 100644

   def format_article_summary(article, format, options = {})

Should be fixed in v3.2.0. @Atmis @thinknot please have a look and verify when you have a moment.
