@lordsnake – At the risk of sounding patronising: –

1. are you sure it’s the single.php template that is being used to render your page? Give it a little tweak in the bp-default theme (you can change it back afterwards) and let us know if it’s being picked up.

2. are you sure your new single.php (child theme) has been published to your server?

3. what happens if you try to override your index.php, does that get picked up?

Failing that: post your folder structure, header from your style.css, and your single.php file for us to check.

Oh, and which version of WP and BP
