I help run a moderately sized BuddyPress based site.
We’re having a problem where all links on the single activity page are being replaced by (embed) links to the activity.
I’ve traced this down to BP_Core_oEmbed_Extension->filter_embed_url and BP_Core_oEmbed_Extension->filter_embed_html, which are called as part of WordPress’ ‘auto-embed’ links (via the post_embed_url and embed_html filters).
AFAICS, these are designed to override the HTML produced when a post is embedded elsewhere, but neither check is_embed().
Does anyone else have this problem, or is it just me?
