I want to delete all comments, but it only lets me bulk delete 100 at a time. If I choose to view more than 100 comments at a time, select all, and move to trash, I get an error saying the request is too large. I have 6,100 comments I have to delete. Do I really have to click “move to trash” and wait for the page to load 61 times?
On certain themes, if you set it to disallow comments on your Settings->Discussion, it used to delete or at least hide all the comments. You could try that first. Sorry, I don’t know which themes, we just got reports of this a few times. And staff may have changed it in the last year.
