Hi imath thank you for the quick reply.

It is a WordPress theme and I think you have identified my mistake, which was a dumb one I am ashamed to say.

I thought I had used option 2) placing a folder called buddypress inside the child theme

I will change to

wordpress-theme/buddypress/activity/index
