I too have a problem. Just made sure (as good as possible) that my plugins are using redmine-acts-as-taggable-on... Somehow migration failes... /home/redmine/redmine/vendor/bundle/ruby/2.1.0/gems/actionpack-4.2.5/lib/action_dispatch/http/mime_type.rb:163: warning: already initialized constant Mime::VCF /home/redmine/redmine/vendor/bundle/ruby/2.1.0/gems/actionpack-4.2.5/lib/action_dispatch/http/mime_type.rb:163: warning: previous...

Okay, after some recherche I found out that there's some mismatch... The expected structure for `taggings` table is ['tag_id', 'integer'], ['taggable_id', 'integer'], ['taggable_type', 'string'], ['tagger_id', 'integer'], ['tagger_type', 'string'], ['context', 'string'],...

After fixing the tables (taggings) and indexes the migrate.rb script runnes without having any errors... So, tried to edit tags within the existing plugin -> works fine... After trying to...

Okay, I haven't written any solution back then. **Solution:** The error message shows what's going wrong in detail: it misses needed columns in the DB. Add those columns (as nullable)...

Have you fixed it, bluenevus? You have to alter the affected table (there should be some columns missing) and everything should work fine

Have you added "tagger_id" and "context" with the appropriate types and as nullable to the table? For me that worked fine (having a redmine installation with running knowledgebase plugin)
