When I'm using Kunena on my site I have problems on the navigation bar.
Whenever I'm in a Kunena "page" the navigation is not showing the FORUM as active.
A work around will be to change the active with java script or jquery
add this script to your index template
<script>
var j = jQuery.noConflict();
var isForumActive = <?php if (strpos($_SERVER['REQUEST_URI'], "/forum") !== false){ echo "true"; } else echo "false";?>;
if(isForumActive){
j(".item120").addClass("active");
}
</script>
You will need to change the id (120) with your menu id and be sure that the alias is the correct.
you need jquery as well....
