BuddyPress strips object and embed tags from my posts entirely.
bp shows an excerpt of the post and the excerpt is stripped of most things. It’s an excerpt. An excerpt is not the post itself. See the link Peter has there for a solution.
I actually modified the theme so that it doesn’t show an empty box if the stripped version is empty. I can’t find where I do that check though, and I’ve looked through bp-activity-widgets.php, bp-activity.php, and bp-activity-classes.php. I’m fairly certain I just check the length of activity and if it’s 0 or null, I don’t create the paragraph element.
NyQuil has my brain foggy today
