Today I looked into the "comment spam" section of my blog and found a comment that is definitely NOT spam but marked as spam. Well, that may happen, so I just clicked the "approve" link below the comment.
It disappeared, but after a second came back in red, and on the bottom of my page it said "You do not have permission to do that.".
I don't understand that, I am the only admin on my blog, and of course have all privileges, so why shouldn't I be able to approve comments?
