may be a good tips for anybody who is in trouble with Publicize,
I’ve found why Publicize is not workingfor me,
I’m using Video Thubnail plugin to add thumbnail in the excerpt on my home page for each posts, but Video Thumbnail doesn’t work if post is not yet published, so I put the post in “Private” mode, go to check the thumbnail, and, update the post to “planned”…
this is the big mistake, because “Publicize” see that the post has already been published (in private mode, but still published)
So “Publicize” is not ok for me, I will uninstall it to try “Network Publisher” who seems to be very very much appreciate to auto-publish posts.
