Comments refusing to post, then appearing afterwards but with no message to say they have apparently gone to moderation.
Was difficult to describe in the title, but a few times recently I have typed out my text but when pressing 'post comment' nothing happens. No message, the page just refreshes with my text still in the box. So I press again, same result. A few minutes later they both appear and I have to delete one. I also get notifications in my activity bar to say they have now 'gone live'.
