Have you tried:
– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the Twenty Eleven theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
This happened even when I used twentyeleven. I do not think any widget is the problem because I’ve disabled and enabled every single one and nothing happens (using the twentyeleven theme I used “Advanced Code Editor”, “One-Click Child Theme” and “TAC (Theme Authenticity Checker)”. And I had this problem even before I installed any of the latest widgets, so I know for a fact that the latest widgets are not the problem.

I have no clue what this means.

This is basic WordPress troubleshooting, Please re-read the suggestions I gave above.
Oh, ok sorry. I tried changing the theme back to twentyeleven and the problem disappeared. But changing back to the platform-theme led the duplicate post problem to come back. What do I do now?
Sorry but it sounds like this is a theme issue.
Hi Danielflo,
I’m have the same problem. Just curious how you fixed it?
Thanks,
Janine
