8 years ago We have handled it by commenting below 4 lines in: https://github.com/alexbevi/redmine_knowledgebase/blob/master/app/helpers/knowledgebase_helper.rb, ...and recreating previously deleted categories.
when "updated"
(:label_summary_updated_articles,
:ago => time_ago_in_words(article.updated_at),
:category => link_to(article.category.title, {:controller => 'categories', :action => 'show', :id => article.category_id}))
But still, I would not close the subject, as issue should not appear in the first place. There sould be some confirmation prompt before deleting not empty category. If so issue will not appear.

Hey Recently I was about to use Knowledge base plugin, installed and everything, but when we started to insert articles at some moment, page threw 500 internal server error. It seems that it was caused by removin category, but person responsible for the issue is unable to exacly explain what he did (so possibly removing category might not be the case).
I will be much obliged for any help with this.
