Undefined offset: 0 in /wp-content/plugins/lh-private-buddypress/lh-private-budd

A bit more specific, this only happens for the home url of the group.

See the BuddyPress codex:
https://codex.buddypress.org/developer/the-bp-global/

$bp->action_variables array
Action variables are all the remaining sections of the URL after $bp->current_action. Each section (chunks of the URL between forward slashes) become an item in the array. For example the URL https://example.org/members/andy/groups/my-groups/leave/15 the values leave and 15 would each be items in the action_variables array.

So where the url is the root of the group then action_variables will be intentionally empty so this code can be expected to fail.

apart from a try block, a more explicit check avoids the problem:

if ( $bp->current_action == 'feed' ){
	$isBuddyPressFeed = true;
}elseif (count($bp->action_variables)>0){
	if ($bp->action_variables[0] == 'feed'){
		$isBuddyPressFeed = true;
	}
}

(I write it out longhand because I feel it is clearer)

However I’m not sure whether this feed check is that useful at all, for example with the feed check enabled, if you try a url like https://mysite/groups/mygroup/feed
if you are not logged in you get the results like:

I’m not sure this is more useful than not having the check
