If page.php doesn't have a div id=content load more breaks

Someone else test this. I tried a custom theme and twenty twelve.

Some themes may not have a id=content div. When no id=content and you click load more the results are not attached to the dom.

Confirmed. We should be using #buddypress for this. Good catch.

The same thing happens with our ajax pagination for groups/members directories, where click events are delegated from #content. I'll fix that too.

(In [6820]) Use #buddypress instead of #content when appending more activity items via AJAX

See #4845
