So you disabled the comment core drupal 7 module but now you get at Log Messages (admin/reports/dblog) this warning:

3 orphaned actions (comment_publish_action, comment_unpublish_action, comment_save_action) exist in the actions table

If you have drush enabled it is really simple to fix this by typing:
drush php-eval "actions_synchronize(actions_list(), TRUE);"
