Attempting to access a non preloaded custom field

#1

Error

See also Site not building after 2.3.0 beta 5. I reported to @angus for Events Plugin 📆. (moved to #support instead of #bug.)

StandardError (Attempting to access a non preloaded custom field, this is disallowed to prevent N+1 queries.) /var/www/discourse/app/models/concerns/has_custom_fields.rb:158:in `[]'

  • Running latest tests-passed (beta5+57)
  • The error appears in safe-mode
