I was having issues with so many "unknown actions" coming up in my "who's online" page after installing this program.

I have figured out how to fix them all!

Firstly, the one regarding individual pages made by the page manager:

Secondly, the one regarding the "home page" and the "index page" I simply replaced the following lines of code in who.english.php with the following:

$txt['who_index'] = 'Viewing the main index of <a href="' . $scripturl . '">' . $context['forum_name'] . '</a>.';

replace with:

$txt['who_index'] = 'Viewing the front page of <a href="' . $scripturl . '">' . $context['forum_name'] . '</a>.';

Then add:

$txt['whoall_forum'] = 'Viewing the index of <a href="' . $scripturl . '">' . $context['forum_name'] . '</a>.';


Might be a good idea to include this with the next install so that actions show up properly.  The page thing will need some extra coding, as I hand coded the page links and names.  Not sure if you can create some script to pull the name of the page and display it.
