RtMedia is not working at all for me.
I have only buddypress, and rtmedia activated with the default theme.
Images do not post to feeds, or add to media gallery.
FIXED!! not sure how but you def need to set a certain setting when initially setting up site and rtmedia. Was not working.
I was wondering though, could tell us more about the setting that you had had to change to get rtMedia running? That would help us avoid such situations in the future!
