Re: Getting the activity feeds “view” link template file correct for custom themes
Broadly speaking? It’s an odd file that permalink.php one 
You will probably need to compare it to the markup for a file such as members/index.php or some similar main template file for your theme. permalink.php has very little markup apart from calling the get_header() and get_footer() in between that you simply have a ul construct and activity/entry.php call so it’s never likely to work well in customised themes without some work.
