So… I was having a brutal bug with WordPress seeming to think that I was logged in when I wasn’t. I tried everything I could think of, turning off all plugins, trying different themes, looking at various database settings. Then, of course, I finally had to just Google what I was looking for. And lo and behold, the exact answer to the problem:

Logged in as . Logout — WordPress Support

Logged in as . Logout
…
try checking your user list to see if you have a blank user added somehow?

That was the answer. I had a blank user in the Users list somehow. I gave the user a user name, then demoted to level 0 so that I could delete.

And now, you can actually comment, sign in and also use the live search functionality on Ajax Blog now! 🙂 🙂 🙂
