I have one strange problem with commenting on my own site, and i'm not quite sure what causes it.
If i go to my own site from within the admin interface, i arrive at my own site Authenticated. So i cannot enter a name when i comment, because my username is already there, and there is no more input field. Submitting a comment is impossible, as it gives me an error ' You should at least give your name or nickname.'
Since i use the remember comment data plugin, there is a way around, by logging out, commenting with any given name, say John Doe, deleting that comment after logging in and commenting again as Authenticated. Strangely it has remembered John Doe, so the comment is now left as John Doe, with my usernames avatar.
As i say, strange. I hope someone understands what i mean
