David,
By “same issue” I meant that I experienced the same problem after I reinstalled the plug-in. The options I selected are not remembered on one post and on another I used the checkbox to try and disable author information. Have not tried it with pages.
I tried the plug-in on a test blog with no other plug-ins activated and the problem persists with this theme.
I tried three other themes on this test blog. It worked perfectly with WordPress Classic 1.5 by Dave Shea and partially with Church and Lifestyle by StudioPress.
