Hi Ezrul,
When I open up the authors tab, yes the correct username is populated in that column. However, when I click on the author to make changes/additions, then the username that is populated is the admin. It is very strange. And the problem is when I change it to the correct username, I have to always add the passcodes. If it doesn't save, which most the time it doesn't, all of the information I added is gone, and I have to start over. Attached is a screen shot of your blog with my admin in the username.
Thank you
