Yes. I remember there's a bug with it lately that when you click on the Edit icon, it takes you back to the blog homepage. To go around that, instead of clicking the Edit icon, right click on it and open link that way. It should work.
Hmm, you don't have the edit button. Unless...it timed out? Like in posts, after a certain moment I'm not sure members can edit what they wrote anymore. Can you make a comment today and see if it's still like that?
