Just wanted to post my solution to this issue, in case anyone else needs it.
I’m using my own theme with buddypress, which means I had to tweak the buddypress files to match my theme’s HTML structure. I used the BP Compatibility plugin to help with this, but the following file needed restructured, which wasn’t listed in the plugin:
Browse to wp-content/themes/YOUR THEME/members/single/activity/permalink.php
Make it match the structure of your theme’s index.php file.
