I went to look but you’re in maintenance mode… but if anything is still there, the only other method would be to add custom css to “display: none;” on anything that has anything relating to comments, or last resort, stripping out the code from several files.
I just found this plugin that disables comments….I just tried this in Preference and sure enough, it took out everything relating to comments.
