Doing a follow up on this thread:

Synced rtmedia content - multisite

Hello! I’m currently developing a bilingual Buddypress multisite project with rtMedia plugin handling photos. The network consists of two identical blogs in different languages (EN + RU; by the way, I’ve almost completed the Russian translation for you guys - plan to finish it in the nearest time). The problem is that rtMedia content between those two blogs inside a multisite WP install is different and I haven’t found the way to make it synced. In other words, when a user uploads a mediafile …

I use WP multisite with subdomain with MultilingualPress, translation is working, everything fine except that the medias don’t display when I switch between 2 languages for the same user profile page but using different subdomain. It display correctly on the subdomain that I upload them, but not in another domain for the same user profile. Any idea?
