I installed multilingual-press v1.02 on WP 3.5 on 12/17 and got it to work fine as a proof of concept.
I started trying to implement this tonight on a new domain using WP 3.5 and multilingual-press v1.02 and it did not work.
Maybe it’s my host (hostgator), but I have no clue as to what’s going on. I’ve set up the blog relationships, but when I create a new page or post there is no linked page or post along with it. I do see the option to “Translate Page (or Post)” though.
I’ve tried adding new dummy pages and posts because one user said that trick helped her. I’ve reinstalled WP 3 times tonight just trying to get this to work. *shrug*
