Looks like you’re using the old deprecated BP theme format.

That’s probably the reason why your activity stream isn’t working properly.

What you’ll need to do is copy over some of the activity code from /wp-content/themes/bp-sn-parent/activity/ to your /wp-content/bp-themes/bpfun_member/activity/.

Don’t do a straight overwrite! Take a look at the code and only copy over parts of it.

Make sure you make backups!
