WPFC Install : Changes to Homepage not reflected

Hello guys,

I have a very weird behavior: I'm migrating a WP site, so installed a new --WPFC install, imported the DB and move the files... then reinstalled W3TC and Nginx-Helper plugin...

All works well, except that changes made to the homepage are NEVER reflected...

• Not as a logged-in user (e.g. I can't preview the changes from WP as an admin)
• Not as a visitor either
• Tried to purge the cache with Nginx-Helper, didn't change anything, as well as using W3TC to purge the memcached objects and DB.

Any idea ?

Thanks a lot,

Cheers,
