Really weird issue here. On category pages, the timestamp is showing instead of the title. Considering everything I've done as documented in these threads, I completely deleted my BP Daily 2.8 child and parent themes, then re-uploaded them. Same behavior.
This only happens when Buddy Press plugin is not activated. When I reactivate the BP plugin, the title shows. I did during today delete the BP plugin then re-download and upload it. Not sure when this behavior started.
