My web site is http://selfhelpforibs.com/
The duplicating Theme is Andreas04 2.0
Switching to another theme does not show any duplication of the posts on the index page.
I have been tweaking galore today, yes. Since the index page started duplicating posts, I have done the following:
**Removed any code crud inserted to make some plugins work.
**Searched this Support site on "duplicate posts" up to 61 entries, and read many of them.
**Deactivated each plugin in turn, then reactivated it.
**Switched out themes
When I switch out themes, *that* problem goes away--so does Google adsense! I'm switching to 3CLR 2CR - SB Blue by Guido Stiehle.
